Valve Back-mounting Collar 1-13878 Waterjet Parts Supplier

The Valve Back-Mounting Collar 1-13878 is a structural support and fastening component used in waterjet valve assemblies and high-pressure systems. Its main function is to securely position and support the valve body from the rear mounting side, ensuring stable alignment and reliable operation during ultra-high-pressure cutting applications.
This mounting collar helps distribute mechanical load, reduce vibration impact, and maintain proper positioning of the valve assembly under continuous pressure cycling and high-speed operation. It plays an important role in protecting connected components from misalignment, loosening, and excessive stress.
A high-quality valve back-mounting collar is essential for maintaining valve stability, accurate flow control, and long-term operational reliability.

Is Valve Back-Mounting Collar 1-13878 a Wear Part?

Yes — the Valve Back-Mounting Collar 1-13878 is considered a semi-wear structural part.
Although it is manufactured from durable high-strength materials, it continuously operates under vibration, pressure load, mechanical stress, and repeated maintenance cycles. Over time, it may experience wear, deformation, thread damage, corrosion, or cracking.
If not replaced when damaged, it can cause unstable valve positioning, leakage, vibration issues, and increased wear on related components.
Regular inspection during maintenance is strongly recommended.
