description

Plastic seal ring is static and dynamic sealing part for hydraulic and drive assembly. It fits tightly into seal groove by elasticity, isolates hydraulic oil and gear oil to avoid leakage, and blocks sand and dust from entering precision mating surfaces. Aging, cracking, notch and extrusion deformation of seal ring will lead to oil seepage, unstable oil pressure and abnormal wear of components.

FAQ 

Q：Can I keep using it temporarily if the seal ring cracks?
A：Not recommended. Crack will cause rapid oil leakage and pressure drop, which may damage internal gears and bearings.

Q：Which direction should the split gap face during installation?
A：Keep the gap away from high-pressure oil impact, follow official assembly drawing, do not face oil inlet.

Q：Can ordinary O-ring replace this plastic seal ring?
A：No. They differ in structure, pressure resistance and wear resistance, replacement will lead to early failure.

Q：Why does the seal ring get crushed quickly after installation?
A：Excessive groove clearance, overpressure and insufficient chamfer /burrs on groove are the main causes.
