Interlock Flat Seal Fitting With Nut & Ferrule Eliminates Leaks in High Pressure Hydraulic System

Hydraulic Fitting Catalogue

A interlock flat seal fitting is a type of hydraulic fitting, designed to be used with a hose tail and provides a secure and leak-proof connection between hoses and pipes or tanks.

Interlock flat seal fittings incorporate an O-ring at the face of the fitting and are designed to eliminate leaks in high pressure hydraulic systems. When the connection is tightened, the O-ring compresses against a flat face sleeve, which has been brazed on the end of a tube. They usually combine with a nut and a ferrule and are usually made of brass or stainless steel. The nut allows easy installation and removal of the hose, while the ferrule on the interlock flat seal fitting ensures a tight seal that prevents leaks.
