Hydraulic Hose Storage Mistakes That Shorten Service Life

Proper storage is critical to keep hydraulic hoses in good condition before installation. Many warehouses store hoses casually, ignoring environmental and stacking rules, which leads to premature aging even before the hoses are put into service.

Common Storage Mistakes

Direct sunlight and UV exposure. UV rays break down rubber molecules, causing outer cover cracking, hardening and loss of elasticity. Windows and outdoor storage areas are not suitable.

High temperature storage. Storing hoses near boilers, heaters or hot pipes accelerates rubber aging. The recommended storage temperature range is between 0°C and 25°C.

Contact with chemicals. Keeping hoses together with solvents, fuels, acids and greases will erode the rubber cover and inner tube.

Heavy stacking pressure. Stacking too high will flatten the hose, permanently deform the inner bore and damage the reinforcement structure.

Hanging hoses for a long time. Long suspension causes gravity deformation, especially for large-diameter hoses.

Storage with sharp metal parts. Sharp edges scratch the outer rubber and create hidden damage.

Ignoring shelf life. Even unused hoses have an expiration date. Long-stored hoses face bonding degradation and cannot withstand rated pressure.

Standard Storage Guidelines

Store hydraulic hoses indoors in dark, dry and ventilated areas. Keep away from heat sources, ozone generators, chemical reagents. Coiled hoses should be stacked at limited height. Do not place heavy goods on top. Mark production date and implement first-in first-out inventory management. Protect hose ends with plastic caps to prevent dust, moisture and foreign particles from entering the hose bore. Avoid twisting during storage.

Inspection Before Taking Out of Storage

Check outer rubber for cracks, stickiness or hardening. Confirm no permanent deformation. If any aging signs appear, test or discard the hoses instead of direct installation.
