Product Description
A one-touch fitting used to connect two pieces of tubing through a panel.
[Features]
· Compact and lightweight with improved tube insertion/removal.
· Suitable for use with nylon and urethane. The chuck grips the workpiece securely, increasing the tube holding force.
· Can be used for pressures from a low vacuum up to 1 MPa. The special profile ensures a reliable seal and minimizes resistance when inserting tubes.
· Requires little force when removing, preventing the chuck from biting too deeply into the tubing.
· Effective when piping in confined spaces. The body and thread part rotate enough to allow for positioning.
[Applications]
· Use to connect tubing through panels, etc.

Product usage precautions
Note 1: Fittings without a thread portion and with all resin bodies are copper free specifications.
Note 2: The surge pressure must be under the maximum operating pressure.
Note 3: Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage.
