Parker 170PTCNS-6-2 Push-to-connect Tube Fitting Brass

Product Description

The PARKER 170PTCNS-6-2 is a brass push-to-connect tube fitting with a female NPT center port, designed for inline tube-to-tube connections with a threaded branch outlet. It accepts 3/8 inch OD tubing on both push-to-connect ends and features a 1/8 inch NPTF female thread. Rated to 250 psi, this fitting is constructed from brass with a nitrile O-ring seal and is compliant with D.O.T. FMVSS571.106, SAE J2494, and SAE J2494-3 standards. It is a general-purpose fitting suited for pneumatic and fluid line assemblies across HVAC, refrigeration, and related trade applications.

This fitting is used in residential and light commercial applications where a push-to-connect tube run must also branch off to a female-threaded port. Typical install scenarios include air lines, control tubing, and fluid transfer systems where fast, tool-free tube connections are required alongside an NPT-threaded component tie-in. The operating temperature range of -40 degrees F to 200 degrees F makes it suitable for a broad range of ambient and fluid conditions encountered in trade service work.

Compatibility

Designed for use with 3/8 inch OD tubing in general-purpose pneumatic and fluid line systems requiring a female NPT branch connection. Suitable for applications conforming to D.O.T. FMVSS571.106, SAE J2494, and SAE J2494-3 standards.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. De-energize and depressurize the system fully before removing or installing any fittings. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect end. Verify that the NPTF thread engagement meets applicable IPC or IFGC requirements for the service application.
