Parker PPB4TMC4 Tube Stem Adapter 1/4 X 1/4 in Od

Product Description

The PARKER PPB4TMC4 is a push-to-connect tube stem adapter designed to create quick, tool-free connections in fluid-handling and pneumatic systems. Manufactured from polypropylene, this fitting is rated to 150 psi and accommodates 1/4 inch outside diameter tubing on both ends. The push-to-connect mechanism allows for fast installation and removal without threaded tools, making it suitable for light-duty plumbing, irrigation, HVAC, and industrial process lines. Technicians and tradespeople working with small-bore tubing runs will find this adapter useful wherever a straight inline or transitional tube connection is required.

This tube stem adapter is suited for residential and light commercial applications where polypropylene construction is acceptable for the media and environment. Common install scenarios include water treatment lines, pneumatic control tubing, HVAC condensate and sensor lines, and general-purpose fluid transfer where 1/4 inch OD tubing is used. It is sold individually and is intended as a direct replacement or new-installation fitting in compatible tube runs.

Installation Notes

Shut off fluid supply and depressurize the line before removing or installing any push-to-connect fitting. Ensure tubing ends are cut cleanly and squarely with no burrs before insertion to achieve a proper seal. Verify the tubing OD is compatible with this fitting before installation. This fitting type is commonly installed by HVAC technicians, plumbers, and irrigation or process technicians working within applicable system pressure limits.
