Parker 371PTCSP-4-4 Push-to-connect Plug-in Run Tee 1/4 in

Product Description

The PARKER 371PTCSP-4-4 is a push-to-connect plug-in run tee fitting designed for 1/4 inch OD tubing. Built from composite material with a nitrile O-ring, it delivers a rated working pressure of 250 psi. The plug-in run tee configuration allows a branch connection to be added inline without cutting or threading the main tube run, making it a fast and reliable choice for pneumatic or fluid distribution lines. HVAC technicians, plumbers, and instrumentation techs use this fitting where quick, tool-free connections are required in tight spaces or during high-volume installations.

This fitting is suited for residential and light commercial applications where composite push-to-connect fittings are specified. Typical install scenarios include compressed air distribution, low-pressure fluid lines, and HVAC control tubing runs. The plug-in run tee allows the main tube to pass straight through while a perpendicular branch line is added at the same point, simplifying manifold and branch-line layouts without additional adapters or unions.

Key Features

• Push-to-connect design for tool-free, fast tube insertion and secure hold
• Plug-in run tee configuration supports inline branching without interrupting the main tube run
• Composite body construction offers corrosion resistance in damp or chemically mild environments
• Nitrile O-ring provides a reliable seal compatible with air, water, and a range of common fluids
• 250 psi working pressure rating suitable for pneumatic control and low-pressure fluid service
• Compact footprint — 2.6 inches length, 4.4 inches width, 1.4 inches height

Compatibility

Designed for use with 1/4 inch OD tubing in push-to-connect pneumatic and fluid distribution systems. Consult system specifications to confirm tube material and pressure rating compatibility before installation.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or instrumentation mechanics as applicable to the system. Depressurize and isolate the line completely before inserting or removing any push-to-connect fitting. Verify tube end is cut squarely, deburred, and clean before insertion to ensure proper O-ring seating and leak-free performance. Follow applicable system and facility codes for pressure line work.
