O-Ring 1-11679-346 Waterjet Pump Parts For Sale

The O-Ring 1-11679-346 is a precision sealing component used in Waterjet Intensifier pump systems. Its main function is to provide a dependable seal between connected components, preventing fluid leakage and maintaining stable pressure within hydraulic and ultra-high-pressure assemblies.
This O-ring is commonly installed in cylinders, valve bodies, manifolds, fittings, and other sealing interfaces where reliable sealing performance is required under demanding operating conditions. It helps protect internal components, maintain pressure integrity, and ensure smooth and efficient system operation.
A high-quality O-ring is essential for reducing leakage risks, improving sealing efficiency, and extending equipment service life.

Is O-Ring 1-11679-346 a Wear Part?

Yes — the O-Ring 1-11679-346 is a consumable wear part.
Because it continuously operates under sealing compression, pressure fluctuations, fluid exposure, temperature changes, and mechanical stress, the elastomer material gradually wears, hardens, cracks, or loses elasticity over time.
If not replaced on schedule, it can lead to leakage, pressure instability, contamination, and reduced pump performance.
Regular inspection and scheduled replacement are strongly recommended.
