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.
Suitable for use with nylon and
urethane.
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 confi ned space.
Body part rotates allowing for positioning.
