Overview
The Aqualon 10257 – Collar 3/8″ – Replaces KMT 10078715, 49864622, 10014667 is a 3/8-inch high-pressure collar used in KMT-style coned-and-threaded tubing assemblies. Collars provide the clamping force required for the gland to seat properly against the cone, forming a secure metal-to-metal seal within high-pressure waterjet plumbing.
Purpose / Why It Matters
In a coned-and-threaded high-pressure connection, the collar is essential for maintaining correct preload on the gland. As collars wear through repeated torque cycles, the hex flats can round, the threads can deteriorate, or the collar may lose its ability to maintain clamp force. These issues reduce sealing reliability, increase the risk of leaks, and make it difficult to achieve a consistent assembly. Replacing a worn collar restores stable, repeatable sealing performance.
Compatibility
This collar replaces KMT 10078715, 49864622, and 10014667. No additional cutting-head or system compatibility is verified.
When to Replace / Service Indicators
Replace the collar when you see worn or rounded hex flats, galling or thread wear, distortion caused by over-tightening, or inconsistent torque retention during assembly. These signs indicate reduced ability to maintain a secure seal within the high-pressure tubing connection.
Common Uses
Suitable for high-pressure waterjet assemblies requiring a 3/8-inch collar matching these KMT OEM specifications. Typical applications include pump discharge plumbing, high-pressure tubing runs, and cutting-head supply lines that use coned-and-threaded fittings.
Why Choose Aqualon
Aqualon 10257 offers a dimensionally accurate replacement for KMT 10078715, 49864622, and 10014667, ensuring reliable sealing performance and straightforward installation within existing 3/8-inch high-pressure coned-and-threaded systems.
