Parker PPB4MC2-MG Push-to-connect Pipe Connector

Product Description

The PARKER PPB4MC2-MG is a push-to-connect tube-to-pipe connector fitting designed for fast, tool-free tube installation in pneumatic and fluid-handling systems. Built from black polypropylene, this fitting accepts a 1/4 inch OD tube on the push-to-connect end and threads into a 1/8 inch NPTF port on the pipe or component side. It is rated to 230 psi and provides a secure, leak-resistant connection without ferrules or compression hardware. HVAC technicians, plumbers, and industrial service professionals use this type of fitting where quick tube connections to threaded ports are needed in low-to-medium pressure applications.

This connector is suited for residential and light commercial pneumatic control lines, instrumentation tubing runs, and fluid distribution systems that use 1/4 inch OD tubing terminating at 1/8 inch NPTF threaded ports. Its compact profile — measuring 1.28 inches in length and 0.69 inches in width — allows installation in tight spaces. The polypropylene body resists corrosion and is compatible with a range of non-aggressive media including air, water, and many mild fluids.

Key Features

Compatibility

Designed as a standard push-to-connect tube-to-pipe connector for systems using 1/4 inch OD tubing and 1/8 inch NPTF threaded ports in pneumatic controls, instrumentation, and fluid distribution applications.

Installation Notes

Install this fitting by hand-threading the NPTF end into the mating port and applying thread sealant tape as appropriate for the media and pressure rating. Ensure tubing is cut cleanly and squarely before inserting into the push-to-connect end — burrs or angled cuts can compromise the internal collet seal. Depressurize and de-energize the system fully before removing or installing any fittings. Follow applicable plumbing or pneumatic codes for the jurisdiction and application.
