Check Valve O-ring 1-11679-131 94K Waterjet Pump Parts Supplier

The check valve O-ring 1-11679-131 is an essential sealing component within the high-pressure check valve assembly of a Waterjet Booster Pump system. Its primary function is to establish a reliable seal between the various components of the check valve, thereby preventing high-pressure water leakage and ensuring stable unidirectional flow during pump operation.
This O-ring must work in conjunction with the check valve body, inlet valve spool, outlet valve spool, valve seat, and other sealing components to maintain pressure stability and protect the entire check valve system from leaks and performance degradation.
Despite its small size, it plays a critical role in ensuring the safe and efficient operation of ultra-high-pressure waterjet systems.

Is the check valve O-ring 1-11679-131 a wear part?

Yes—the check valve O-ring 1-11679-131 is a typical wear part.
Because this O-ring is constantly subjected to ultra-high pressure, water flow impact, repeated sealing contact, and stresses caused by valve movement, it will gradually exhibit signs of aging over time, such as wear, hardening, cracking, or loss of elasticity.
Failure to replace it in a timely manner may lead to malfunctions such as leaks, backflow, pressure fluctuations, and reduced cutting performance.
Therefore, it is strongly recommended to inspect this component regularly and replace it promptly.
