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 profi le 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
confi ned space.
Body part rotates allowing for
positioning.
