description

This NBR O-ring is integrally molded with stable rebound performance, designed for fluctuating hydraulic pressure and frequent cycling. It is widely used for static sealing on valve blocks, tube fittings and end caps. Aging, indentation, extrusion tear and swelling will trigger pressure drop, slow response and oil seepage. Ingress contaminants may scratch valve bore and grooves and cause persistent hydraulic faults.

Type: O-ring seal
Material: NBR nitrile rubber
Color: Black
Compatible Fluid: Anti-wear hydraulic oil, transmission oil
Not for: Strong corrosive solvent, high-temperature fuel
Working Condition: Medium pressure and cyclic fluctuation for hydraulic circuit
Matching System: Static sealing for hydraulic valve, cylinder and fittings

Application Scenarios

Fits Caterpillar wheel loaders, excavators and bulldozers, for overhaul of static sealing positions on hydraulic valve, cylinder and fittings

FAQ 

Q：Can slightly flattened O-ring be reused if it looks intact?
A：Not recommended. Permanent compression set reduces rebound and leakage is likely under pressure.

Q：Can this O-ring replace seals with different cross-section size?
A：No. Cross-section determines compression ratio, wrong size causes crush or poor sealing.

Q：How to solve O-ring damage caused by sharp groove edge under high pressure?
A：Install backup ring or improve groove radius to avoid shear extrusion damage.

Q：Why does fitting still leak after new O-ring installation?
A：Check scratch on sealing face, loose thread and misalignment, structural damage cannot be fixed by seal replacement.
