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).

Guide
∗1 The surge pressure must be under the maximum operating pressure.
∗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).
Drastically reduces
screw-in time with the
face seal method.

Face seal method
Can be used for a wide range of
pressures from a low vacuum
up to a pressure of 1 MPa.
The use of a special profile ensures
sealing and reduces resistance when
the tube is inserted.
