Product Description

A flame retardant (UL-94 standard V-0 equivalent) one-touch fitting for perpendicular piping.
[Features]
· Supports FR soft nylon.
· The collet maximizes the retention force. The chuck engages the work piece securely.
· Its special shape ensures a secure seal and minimal resistance when inserting a tube. Can be used in everything from low vacuums to 1 MPa.
· Effective for piping in tight spaces.
· The body and threaded section can be rotated enough to allow for positioning.
[Applications]
· Can be used to connect piping in a perpendicular orientation from female threads.
