Parker X639PLP-6 Push-to-connect Plug 3/8 in Od

Product Description

The PARKER X639PLP-6 is a push-to-connect tube plug fitting designed to cap and seal 3/8-inch OD tubing without tools. It accepts tubing with a 3/8-inch outside diameter and holds a rated working pressure of 150 psi. The fitting is constructed from plastic and features an orange color for quick visual identification in pneumatic or fluid line applications. Installation requires only hand pressure to engage the internal collet and seal. HVAC technicians, plumbers, and pneumatic system installers use this type of plug to terminate or temporarily block tubing runs during service or system modifications.

This plug fitting is suited for use in low-pressure pneumatic lines, fluid distribution systems, and light-duty process plumbing where push-to-connect termination is preferred. The compact plastic body keeps weight minimal and resists corrosion in moisture-present environments. It is commonly installed in residential and light commercial settings where quick disconnect and reconnect capability is needed during servicing of tubing networks.

Push tubing or insert the plug firmly into the fitting body until the collet engages and the connection is secure. To remove, depress the release collar and pull the fitting free. Follow applicable plumbing and pneumatic codes for the jurisdiction where the work is performed.
