Hydraulic Hose Crimping

August 26, 2021


A well-crimped seal is essential to a functional and efficient
hydraulic hose. But just how does the job get done?


A good, tight, even
crimp secures the hose connector in place and allows the fluid to move through freely without leaks. To properly crimp your hose, you’ll need a crimper that is designed for use on a specific hose diameter. You should choose your crimper based on the hose you’ll be using, not the other way around.


When assembling your hydraulic hose setup, you should choose an appropriate hose based on a few factors: size, temperature, application, media and pressure. While these factors are all important to the functionality of your hydraulic system, size dictates which crimper you’ll use to 
secure the fitting. The hose size is measured in diameter, and the one you choose can affect the cost, pressure capability, rate of flow, and operational efficiency. 


The Tools



To crimp a hydraulic hose, you can use one of two methods: hand crimping or hydraulic crimping. Both are equally effective and can yield high-quality crimps, but which one you use depends on your performance needs (including crimp force and maximum crimp, the materials being used, and sometimes even the brand of hose and/or equipment being used.


Hand crimpers

As their name would suggest, these tools are manually operated. Their portability and relative ease of use make them ideal for small-scale crimping jobs. Hand crimpers are most often used for piecework, low-volume manufacturing, and mobile assembly. Most welders and electricians will carry around a hand crimping device in their toolbag. The device has a tray that opens up, and you can slot in the appropriately-sized crimper dies for the job, meaning they’re pretty versatile and simple to use. 


The downside of these handheld tools is that they are slightly less precise than their hydraulic-powered counterparts. Hydraulic tools employ something called ‘automatic crimp diameter’ measured in micrometers, which ensures the closest, most precise crimp on the hose. Hand crimpers simply rely on the good judgment of the user, and although they’ll get the job done, ultra-fine and exact crimping may be better achieved using a hydraulic-powered device.


Hydraulic crimping tools

Hydraulic crimping tools are considerably more expensive than hand crimping tools, but they are also far more effective for crimping high-volume runs. These tools are preferable for demanding industrial environments, where crimping is a regular operation, and heavy-duty machinery is needed for maximum speed and precision. 


These devices are typically much larger, heavier, and more sophisticated than their handheld counterparts. It’s also faster and more powerful, capable of churning out multiple tight, exact crimps at relative speed. However, some hydraulic crimping tools have limited versatility, as the crimping dies compatible with the machine strongly encourage the user to source parts from the same manufacturer.

On November 8th, 2023, the US Bureau of Labor Statistics released its annual report on workplace injuries. Private industry employers reported 2.6 million nonfatal workplace injuries and illnesses in 2023. This report underscores the importance of preparing for workplace challenges, especially during the winter when injuries rise due to cold, winter weather, and slippery surfaces. Gulf Coast winters bring extreme temperature fluctuations, sudden cold snaps, heavy rain, and high humidity. High-quality personal protective equipment (PPE) and safety supplies protect against the various hazards these conditions present. Ensure your oil and gas workers have these items on hand to keep them safe and productive. Insulated and Weatherproof Jackets Sudden drops in temperature or prolonged exposure to cooler temperatures can impair a worker’s focus, dexterity, and reaction time. Thermal insulation maintains body warmth while waterproof coatings protect against rain and damp conditions. These prevent discomfort and the risks associated with wet clothing, such as hypothermia or reduced mobility. If your workers are often near heavy machinery or fleet vehicles, consider looking for high-visibility jackets with ANSI-compliant reflective strips. They are designed to remain effective even in wet or overcast weather. Workspace-Specific Insulated Gloves Choose gloves that combine the features your workers need in their tasks. You may need gloves suitable for different responsibilities or areas of the workplace. Some features to consider include: Chemical-resistant gloves protect against hazardous materials like acids and solvents. Insulation keeps hands warm, preventing cold-related injuries that impair grip and coordination. These are essential for workers who will work outdoors or in cold indoor areas for extended periods of time. Shock insulation is good for those who work near machinery and electrical components. Anti-vibration gloves reduce the harmful effects of vibration on hands and arms while using power tools or machinery. Cut resistance protects against sharp objects when at work. Good cut protection is considered anything rated A3 and lower. Flexible designs ensure dexterity for precision tasks like repairs and maintenance. Choosing the right gloves will help keep your workers safe from winter weather and the unique challenges of their workplace. High-Traction, Insulated Boots Even without rain or sleet, temperatures can dip low enough to freeze dew and condensation, creating near-invisible slippery surfaces. Boots should feature slip-resistant soles with high traction scores, designed to grip wet, oily, or icy surfaces. Look for acid- and chemical-resistant materials in boot construction to prevent damage and ensure durability in harsh environments. Reinforced-toe options can protect workers from falling objects and other hazards. Insulation prevents cold-related numbness that can affect balance and safety. Hand Sanitizer for Workplace Hygiene and Safety In colder months, workers may be less inclined to wash their hands regularly due to limited access to warm water at job sites. Hand sanitizer provides a convenient alternative to reduce the spread of germs and maintain cleanliness. Choose sanitizers with at least 60% alcohol for maximum effectiveness against bacteria and viruses. Non-greasy formulas are ideal to avoid slippery hands when using tools or operating equipment. Station hand sanitizer dispensers near fleet vehicles, tool storage areas, and break rooms to encourage frequent use without disrupting workflows. Essential Items for First Aid Kits to Treat Cold-Related Injuries Cold-related injuries are rare but possible during Gulf Coast winters, especially when workers are exposed to wet and chilly conditions for extended periods. Make sure your first aid kits are equipped for these during the winter months. Thermal Blankets . Compact, heat-reflective blankets provide immediate warmth to prevent or treat hypothermia in exposed workers. Heat Packs . Disposable or reusable heat packs help warm extremities like fingers and toes. Frostbite Cream or Gel . Specialized treatments for frostbite help minimize damage while waiting for professional medical attention. Cold Weather Bandages . Adhesive bandages that stick even in cold or damp conditions will help protect cuts and scrapes. Extra tape and flexible gauze rolls are also recommended in case of slips and falls. Regularly inspect and replenish first aid kits to ensure all items are in good condition and ready for use. Fire Extinguishers for Heated Areas Indoor and outdoor heating equipment increases fire risk during the colder months. Having the right extinguisher in the right place can make a huge difference in the severity of a fire incident. Ensure extinguishers are rated for the types of fires common in heated areas. They fall under five classifications based on the type of fire they are best suited for. Class A for non-metallic materials like wood, paper, cloth, trash, and plastics Class B for flammable liquids like gasoline and oils. Class C for electrical fires, often caused by space heaters or malfunctioning equipment. Class D for Metal fires involving magnesium, sodium, potassium, and sodium-potassium alloys Class K for fires involving cooking oils and deep fryers. Position fire extinguishers within easy reach of heaters, furnaces, or other fire hazards to ensure workers and responders can react quickly in an emergency.

Moisture can cause corrosion, weaken the hose structure, and eventually lead to costly system failures. Here are some of the risks of moisture damage and some actionable steps to protect your hydraulic hoses in the Gulf Coast area.  Why Moisture Is a Threat to Hydraulic Hoses in the Gulf Coast Region Water enters your hydraulic system through cracks, weak connections, humidity, storm damage, and other factors, leading to various issues. Some notable issues include Corrosion of Metal Components. Moisture causes rust and corrosion on metal parts like fittings and reinforcements, weakening the hose structure and leading to failures. Degradation of Hose Material. Moisture can work its way into cracks and scratches on the hoses, causing swelling, softening, or widening cracks. These issues can lead to leaks or ruptures. Water Contamination in Hydraulic Fluid. Moisture entering the system can contaminate hydraulic fluid, reduce lubrication, create rust inside the components, and cause premature wear of critical parts. Freezing Risk. In cooler conditions, moisture inside hoses can freeze, leading to cracks and clogs within the hose system. Microbial Contamination. Warm, moist conditions can promote bacterial and fungal growth inside hoses, leading to biofilms that clog systems and degrade components. Signs of Moisture in Hydraulic Hoses Detecting moisture damage early can save your business from costly repairs or downtime. Look for these common signs of moisture-related issues during visual inspections. Cloudy or Milky Hydraulic Fluid. When water is present in your hydraulic fluid, it can appear cloudy, milky, or discolored. Corrosion on Metal Parts. Look for rust or corrosion on metal fittings, couplings, or any exposed hydraulic system parts. This can indicate that moisture has entered the system. Deformations in the Hose. Moisture can cause the inner lining of hydraulic hoses to swell or soften, leading to bulging, deformation, or changes in hose flexibility. If these deformations freeze in cold weather, they can further weaken the hose and cause it to burst. Unusual Operating Temperature. Excessive moisture in the hydraulic fluid can reduce its heat transfer capabilities, causing higher temperatures, changes in viscosity, and other issues. Foaming or Bubbles in Fluid Reservoir. When water and oil flow through the system together, they emulsify (break into tiny droplets). If this occurs, it will look like foam or visible bubbles in the fluid reservoir. Preventing Moisture Damage in Hydraulic Hose Systems Premature wear and moisture damage can be prevented without expensive system changes. Here are a few practical things you can do to extend the life of your hydraulic hoses. Store Equipment Properly Keep your hydraulic hoses and equipment covered or in dry, sheltered environments to reduce moisture exposure. If you store your inventory outside, consider using protective coverings like tarps or wraps. If your area is prone to flooding, make sure your inventory is stored above ground level and avoid places where water could pool around them. Regularly Inspect Hoses and Fittings Check hoses for cracking, rust, or leaks after storms or excessive seasonal temperature changes. Make sure to inspect the fittings and connections in the process. Install a Hydroscopic Breather Water can enter hydraulic systems through the reservoir breather during fluid changes. Switching a standard breather cap to a hygroscopic breather prevents this by filtering out particles and absorbing moisture from the air. Check For Proper Hose Installation Improper installation leaves your hydraulic hoses vulnerable to moisture damage. Be sure that your hoses are routed correctly and that fittings are securely tightened. If you need help with the proper parts or installation techniques, consult an expert who can help optimize your system. Action Supply Can Help You Optimize Your Hydraulic Systems Moisture damage is just one of many issues that can affect your hydraulic hose systems. We will recommend the right oil to handle seasonal temperature fluctuations, the right fittings to avoid leaks and issues, and even provide inventory management services to ensure you have the parts you need.
