Cylinder O-ring 1-11679-044 Waterjet Pump Parts Price

The Cylinder O-Ring 1-11679-044 is a precision sealing component used in Waterjet Intensifier pump cylinder assemblies. Its main function is to provide a secure seal between the cylinder and connected components, preventing hydraulic fluid or high-pressure water leakage during operation.
This O-ring is specifically designed for cylinder sealing applications where stable pressure retention and reliable sealing performance are required under demanding operating conditions. It helps maintain pressure integrity, protect internal components, and ensure smooth operation of the intensifier system.
A high-quality cylinder O-ring is essential for maintaining pump efficiency, reducing leakage risks, and extending equipment service life.

Is Cylinder O-Ring 1-11679-044 a Wear Part?

Yes — the Cylinder O-Ring 1-11679-044 is a consumable wear part.
Because it continuously operates under sealing compression, pressure variation, 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 cause leakage, pressure instability, contamination, and reduced pump performance.
Regular inspection and scheduled replacement are strongly recommended.
