description

The O-ring is widely used on equipment housings, flanges and pipe joints. It fills groove clearance by elastic compression, suitable for hydraulic and lubricating oil, with good oil resistance, extrusion resistance and low compression set. Crack, nicks, swelling and aging will lead to oil leakage and pressure drop, and muddy contaminants will speed up wear of gears, bearings and plungers.

FAQ 

Q：Can the O-ring with light squeeze marks be installed?
A：Not recommended. The marks indicate permanent deformation and poor rebound, leading to slow oil seepage under pressure.

Q：Can generic O-rings of the same size replace this Cat part?
A：Use caution. Different compound and hardness may cause swelling or early aging, use matched material preferentially.

Q：What risk will overstretching bring during installation?
A：Reduced cross-section and insufficient compression, which causes leakage after operation.

Q：Will new O-ring fix leakage if the mating surface has pinholes?
A：No. Pinholes form permanent leakage path, repair the housing surface first.
