How to Winterize Hydraulic Hoses of Construction Equipment

November 27, 2023

It's essential to prepare the hydraulic hoses of your construction equipment for the cold season, especially if any part of your equipment will be exposed to severe winter weather and temperatures. Otherwise, you risk mechanical issues and equipment failure that result in costly repairs and downtime. Here are some steps you can take to protect your hydraulic hoses from winter weather.


Inspect and Clean Hydraulic Hoses



Begin by thoroughly inspecting all hydraulic hoses to ensure they are in working order. Look for any signs of:


  • Normal wear and tear
  • Damage to the hoses, fittings, and fasteners
  • Signs of incompatible fittings
  • Leaks
  • Kinks or too much torsion in the line
  • Signs of abrasion from friction
  • Inconsistent pressure or signs of blockages
  • The hose specifications ensure that they can withstand the closest temperatures that they could possibly be exposed to.


Replace or repair damaged hoses and faulty parts. Clean both new and existing hoses and connections to remove dirt, debris, and contaminants.


Check Hydraulic Fluid and Lubricate Parts


Cold weather can affect hydraulic fluid's viscosity, so make sure the fluid in your construction equipment is suitable for the temperature and weather conditions they will be exposed to. Consult your equipment's manual or supplier for specific recommendations.


Proper lubrication is vital in cold weather to keep your construction equipment working smoothly. Lubricate all moving parts, such as joints, pistons, and cylinders, according to manufacturer instructions for winter weather. Replace any parts that may not be suitable for freezing temperatures, ice, and other environmental factors. These steps will prevent parts from freezing and seizing up in the cold.


Protect Exposed Hoses


Exposed hydraulic hoses are susceptible to freezing and damage in winter. Their porous surfaces can become brittle and crack as they are exposed to extreme or fluctuating temperatures. To prevent cracks and leaks: 


  • Use insulated wraps and sleeves to create a barrier between exposed pipes and winter weather. 
  • When feasible, use temporary shelters or outdoor heaters during unusual weather patterns to protect vulnerable areas.
  • Make sure they are sheltered from heavy snow and ice deposits that could put extra strain on their fasteners and lower their fluid temperatures.
  • Inspect any exposed and sleeved pipes after extreme weather storms.
  • If possible, actively monitor fluid temperatures for signs the hydraulic hoses are compromised.


These protective measures will maintain the hoses' flexibility and prevent cracking.


Run and Shelter Equipment and Spare Parts


Letting equipment and hoses sit unused in freezing conditions risks frozen parts, ice buildup, blockages, and other issues. Store your spare parts and unused construction equipment in a dry, climate-controlled indoor space. 


Extra care of resting equipment is necessary to prevent hydraulic fluid from becoming too thick and sluggish in cold temperatures. Start and run your equipment regularly, even if you do not plan to use it immediately. Before using equipment that sat unused in the cold, run it for about an hour to warm the parts and fluid before using.


Be Prepared for Emergencies


Despite your best efforts, emergencies can still happen in winter. Always have a cold-weather emergency kit on hand, including spare hydraulic hoses, hydraulic fluid, and necessary tools for quick repairs. Also, make sure you have a supplier who can provide expert advice and parts fast.

Spring is here, and that means longer workdays, increased demand, and unpredictable Gulf Coast weather. Whether you're in construction, industrial maintenance, or fleet operations, this is the season to get ahead of equipment maintenance before the heat, humidity, and workload take a toll. At Action Supply, we know downtime isn’t an option. That’s why we’ve put together this spring maintenance checklist to keep your equipment running efficiently, safely, and reliably all season long. 1. Inspect Your Equipment: Catch Issues Early The first step in spring maintenance is a full equipment inspection. Look for: Leaks or fluid loss – Check hydraulic lines, hoses, and seals for wear. Rust or corrosion – The Gulf Coast’s humidity speeds up deterioration. Apply protective coatings where needed. Tire & track wear – Construction sites and rough terrain cause excessive tread wear. Electrical connections – Moisture buildup can lead to short circuits or malfunctions. Pro Tip: Preventative maintenance is always cheaper than emergency repairs. Schedule routine inspections now to avoid costly downtime later. 2. Protect Against Corrosion & Rust The heat, salt air, and high humidity in the Gulf Coast accelerate rust and corrosion, which can weaken equipment and reduce efficiency. Be sure to: Apply anti-corrosion sprays to exposed metal parts. Store equipment properly when not in use to limit moisture exposure. Use high-performance lubricants to reduce friction and wear. Action Supply has a full selection of lubricants, protective coatings, and rust inhibitors to help extend the life of your equipment. Talk to our team for recommendations! 3. Keep Lubricants & Fluids in Check With rising temperatures, oil, grease, and hydraulic fluids work harder to keep machinery running smoothly. Check and replace: Engine oil – Prevent overheating & engine wear Hydraulic fluid – Ensure smooth, responsive operation Gear oil – Protect against friction damage Coolants – Keep engines from overheating in Gulf Coast heat Action Supply carries high-quality lubricants designed to handle extreme conditions. Stock up now before peak season hits! 4. Clean & Protect Your Equipment Spring cleaning isn’t just for homes—it’s essential for keeping heavy machinery, trucks, and tools in top shape. ✔️ Pressure wash equipment to remove dirt, debris, and buildup. ✔️ Clear air filters to improve engine performance. ✔️ Check radiators & cooling systems to prevent overheating. ✔️ Inspect and replace worn belts and hoses before they break. Pro Tip: A clean machine is an efficient machine. Regular maintenance extends the life of your equipment and improves safety. 5. Prepare for Spring Storms & Extreme Heat The Gulf Coast is known for sudden storms and extreme temperatures. Be prepared by: Storing backup parts and supplies in case of emergency repairs. Ensuring generators & backup power sources are operational. Keeping emergency safety gear stocked and accessible. Need help finding the right supplies? Action Supply has everything from industrial tools to safety gear to keep your crew prepared.
