Parker PPB6TPL Push-to-connect Tube Plug 3/8 Inch Od

Product Description

The PARKER PPB6TPL is a push-to-connect tube plug fitting designed to seal off an open 3/8-inch OD tube end quickly and without tools. Constructed from black polypropylene, it is rated to 150 psi and suited for low-pressure pneumatic, fluid transfer, or instrumentation lines where a port or tube run needs to be capped temporarily or permanently. Licensed plumbers, HVAC technicians, and industrial maintenance technicians install this type of fitting during system commissioning, pressure testing, or branch-line isolation. The push-to-connect mechanism allows fast, tool-free insertion while maintaining a reliable seal within its rated pressure range.

This plug fitting is appropriate for use in residential and light commercial applications involving tubing systems that require a sealed termination point. Typical scenarios include capping unused ports on manifolds, sealing branch lines during phased installation, or isolating a section of tubing during service. The polypropylene body makes it compatible with a range of non-aggressive fluids and compressed air service. It is sold and packaged as a single unit.

Installation Notes

Shut off system pressure and bleed the line before inserting or removing the plug. Ensure the tube end is cut cleanly and squarely, and that it is free of burrs before seating it into the fitting. This fitting is intended for use within its rated 150 psi pressure limit. Installation is typically performed by licensed plumbers, HVAC technicians, or qualified industrial maintenance personnel following applicable codes.
