Specifications
Principal Parts Material
∗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.
One-touch IN/OUT
connection.
Possible to use in
vacuum to -100 kPa.
Drastically reduces
screw-in time with the
face seal method.
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.
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.
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.
Body part rotates allowing for
positioning.
