Structural Drawing

Guide/chuck
Can be used with both nylon and urethane. Large holding force. The chuck provides a definite grip, greatly increasing the tube holding force.
Seal
Thanks to the unique shape that can be used from a low vacuum up to 1 MPa, there is a reliable seal and low resistance when inserting a tube.
Release bushing (white)
Light removal force. The chuck prevents unnecessary gripping pressure on the tube.
Body/O-ring/stud
Effective for piping in tight spaces. The body and threaded part rotate, allowing for positioning.

Applicable tubing

Tube materialsFEP, PFA, nylon, soft nylon, polyurethane
Tube outer diameterø4, ø6, ø8, ø10, ø12, ø16
