Face seal Applicable Tubing Specifications Principal Parts Material Suitable for use with nylon and urethane. Large retaining force. The chuck provides secure retention and the collet increases the holding force on the tube. Requires little force for removal. Releases the chuck collet to remove the tube as well as to prevent the chuck from biting too deeply into the tubing. Effective when piping in a confined space. The body and the threaded portion can rotate (for positioning to some extent). Seal Stud Release button O-ring Body Piping installability is improved by changing to the face seal structure. Seal ring Chuck Guide Note 1) The surge pressure must be under the maximum operating pressure. Note 2) Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage. Applicable to parallel pipe thread (G). New thread for piping that drastically reduced the screw-in time thanks to the face seal method.

The use of a special profile ensures sealing and reduces resistance when the tube is inserted. 65
