Parker 372PTCSP-4-4 Plug-in Branch Tee 1/4 Inch Od

Product Description

The PARKER 372PTCSP-4-4 is a push-to-connect plug-in branch tee fitting designed for tube-to-stem tube connections in pneumatic and fluid handling systems. Built from composite construction with a nitrile O-ring, this fitting accepts 1/4 inch outside diameter tubing and is rated to 250 psi. The plug-in branch tee configuration allows a branch line to be added to an existing tube run without cutting or crimping, making it a practical choice for routing compressed air, water, or compatible fluid lines. HVAC technicians, plumbers, and industrial maintenance professionals install this type of fitting during system assembly or when adding branch connections to pressurized tube circuits.

This fitting is suited for residential and light commercial applications where quick, tool-free tube connections are required. The push-to-connect design speeds up installation in tight spaces and reduces assembly time compared to traditional compression or flare fittings. It is commonly used in pneumatic control lines, refrigeration tubing assemblies, and plumbing distribution manifolds where 1/4 inch OD tubing is the specified tube size.

Key Features

• Push-to-connect plug-in branch tee design allows tool-free tube insertion for fast assembly
• Rated to 250 psi for use in pressurized pneumatic and fluid systems
• Composite body construction offers corrosion resistance and light weight
• Nitrile O-ring sealing provides reliable performance with air, water, and compatible media
• Accepts 1/4 inch OD tubing — a standard size across pneumatic and HVAC control circuits

Compatibility

Designed as an OEM-style push-to-connect replacement or addition fitting for pneumatic and fluid systems using 1/4 inch outside diameter tubing.

Installation Notes

Depressurize and isolate the tube circuit completely before removing or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the fitting to achieve a proper seal. This fitting type is installed by HVAC technicians, plumbers, and industrial maintenance personnel following applicable system pressure guidelines. Verify the fitting pressure rating is compatible with the operating pressure of the system before placing it in service.
