Valve Fitting Ring | 3/8" | HP Integrated On/Off Valve | HJ-300669
The HJ-300669 Valve Fitting Ring, also known as a mounting collar is a precision-machined stainless steel component designed for use in the 3/8-inch high-pressure integrated On/Off valve assembly found on OMAX waterjet cutting systems. This fitting ring securely retains and aligns critical valve components, ensuring a leak-free, high-pressure seal while maintaining proper valve alignment during operation. It is an essential part of the On/Off valve assembly and contributes to reliable water flow control, consistent cutting performance, and maximum system uptime. It is commonly used in the Integrated On/Off Valve Assembly (HJ-301501).
Manufactured from high-strength, corrosion-resistant stainless steel, the HJ-300669 Valve Fitting Ring is engineered to withstand the demanding conditions of ultra-high-pressure waterjet systems. Precision machining ensures an exact fit, allowing for straightforward installation without modification.
This HJ Waterjet replacement HJ-300669 Valve Fitting Ring is ideal for preventive maintenance, scheduled valve rebuilds, or replacing worn or damaged components that may cause leakage, misalignment, or inconsistent valve operation.
