Applicable Tubing
Specifi cations
Principal Parts Material
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 profi le
ensures sealing and reduces
resistance when the tube is
inserted.
Effective when piping in a confi ned 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 fi ttings with a leak tester or for vacuum retention because they are not guaranteed for zero
leakage.
A ridge shape has been created as a
Uni thread for common applications
for Rc, G, NPT and NPTF.
Drastically cuts piping work-hours
with the gasket seal method.
Uni thread
Uni thread ridge shape
A gasket made of a stainless sheet covered with laminated
NBR on both sides is seated on the chamfer of a female
thread for a perfect sealing construction irrespective of the
difference in thread diameters due to the difference in the
types of female threads, variation in tolerance, or difference
in the size of chamfer. (It is applicable to any female thread
with an ordinary chamfer.)
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.
