Structure
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.
