Parker 371PTCSP-6-6 Plug-in Run Tee 3/8 Inch Od Brass

Product Description

The PARKER 371PTCSP-6-6 is a push-to-connect plug-in run tee tube fitting designed for quick, tool-free branch connections in pneumatic and fluid transfer lines. Built from brass with Buna-N seals and a nylon body component, this run tee accepts 3/8 inch OD tubing on all ports and holds a maximum working pressure of 250 psi. It is sized for compact installs with an overall length of 2.25 inches. Licensed tradespeople and fleet maintenance technicians install this fitting in air brake, pneumatic control, and fluid line assemblies where a reliable inline tee connection is required without threaded fittings or ferrule compression work.

This fitting is suited for residential and commercial HVAC pneumatic controls, vehicle air brake systems, and industrial fluid handling lines. Its plug-in design allows tubing to seat and lock with a straight push, reducing assembly time on the bench or in the field. The operating temperature range of -40 degrees F to 200 degrees F covers most HVAC mechanical room, under-hood, and outdoor installation environments. Plumbers, HVAC technicians, and fleet maintenance professionals working with 3/8 inch OD polyamide or nylon tubing will find this fitting appropriate for inline tee branch work.

Installation Notes

Installation requires cutting the tubing square and ensuring the cut end is clean and burr-free before inserting into the fitting port. Depressurize and isolate the line completely before disconnecting or installing any push-to-connect fitting. Follow all applicable SAE and D.O.T. guidelines for air brake and pneumatic line assembly. Inspect the tubing OD for scoring or out-of-round conditions that could compromise the internal seal.
