Parker PP6TPL Push-to-connect Plug 3/8 Inch Od

Product Description

The PARKER PP6TPL is a push-to-connect tube fitting plug designed to cap or terminate open tubing ends in pneumatic and fluid-handling systems. Constructed from polypropylene, this plug handles pressures up to 150 psi and is rated for 3/8 inch outside diameter tubing. Installation requires no tools — the push-to-connect mechanism locks tubing securely without threading or crimping. It is a standard component used by plumbers, HVAC technicians, and industrial maintenance professionals when isolating lines or capping unused ports during service, installation, or system modification.

This plug is suited for use in residential and light commercial fluid and pneumatic tubing systems where polypropylene compatibility is required. Its tan coloring and polypropylene construction make it appropriate for applications involving water, compressed air, and many non-aggressive chemical lines. It is commonly installed during new construction, system expansion, or service calls where a tube end must be sealed temporarily or permanently.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified maintenance personnel. Before installing or removing any tube fitting, depressurize and isolate the line completely. Push tubing firmly into the fitting until it seats against the internal stop to ensure a secure connection. Verify the system pressure does not exceed the rated 150 psi limit for this fitting before returning the line to service.
