Parker 139PLP-12M Push-to-connect Plug Fitting 12mm

Product Description

The PARKER 139PLP-12M is a straight push-to-connect plug fitting designed to seal off a 12mm outside diameter tube line quickly and without tools. Constructed from nickel-plated brass with a silicone-free grease lubricant and a UL94 V-0 rated body, this fitting handles working pressures up to 300 psi across a temperature range of 0 degrees F to 200 degrees F. The yellow release button identifies it as a plug-in style termination fitting. HVAC technicians, plumbers, and fluid-system installers use it to cap pneumatic or fluid lines cleanly and securely during service or system modification.

This fitting is suited for light industrial, commercial, and residential applications where a push-to-connect tube plug is needed on a 12mm OD line. Typical use cases include capping pneumatic control lines, fluid distribution manifolds, and HVAC refrigerant-adjacent tubing assemblies where a tool-free, leak-tight termination point is required. The silver-body, yellow-button color scheme is standard for quick visual identification in multi-line installations.

Compatibility

Designed for use with 12mm outside diameter tubing in push-to-connect pneumatic and fluid line systems requiring a straight plug termination fitting.

Installation Notes

Install by inserting the prepared tube end squarely into the fitting until it seats fully against the internal collet. Before servicing any line, relieve system pressure and shut off the fluid or air supply at the source. To release the tube, depress the yellow release button and pull the tube straight out. This fitting is intended for installation by qualified HVAC technicians, plumbers, or instrumentation technicians following applicable system codes and manufacturer guidelines.
