Stainless steel pipe bushing

The 316L hose insert—also known as a hose liner or core—is a hollow, cylindrical metal internal support component. Installed inside PU, PTFE, or nylon hoses, it provides internal support and maintains the hose's shape during the fitting crimping process. It prevents the hose from shrinking or collapsing under pressure and protects the hose end from being cut by the fitting's edge, thereby ensuring a secure connection and an unobstructed flow path; it is an essential component for hose assembly.
