Parker 172PTCNS-8-8 Male Branch Tee 1/2 in Od Npt Brass

Product Description

The PARKER 172PTCNS-8-8 is a push-to-connect rigid male branch tee tube fitting designed for use in compressed air and pneumatic plumbing systems requiring a reliable, leak-resistant connection. Constructed from brass, this fitting connects a 1/2-inch OD tube on two ports to a 1/2-inch male NPT thread on the branch port. It carries a maximum working pressure of 250 psi and is rated for temperatures from -40 degrees F to 200 degrees F. The fitting is designated as a D.O.T. air brake fitting, meeting stringent federal motor vehicle safety and SAE standards. Licensed plumbers, fleet service technicians, and HVAC pipefitters install this type of fitting in both stationary and mobile pneumatic systems.

This fitting is suited for air brake tubing circuits, compressed air distribution lines, and other pneumatic plumbing runs where a branch tee with a male NPT takeoff is required. The push-to-connect design allows fast field assembly without the need for ferrules, compression sleeves, or additional sealant on the tube side. It is commonly installed in commercial vehicle air brake systems, industrial compressed air networks, and heavy-duty mobile equipment pneumatic circuits. The nitrile O-ring provides a reliable dynamic seal across the rated temperature range.

Compatibility

Designed as a D.O.T.-compliant air brake fitting for use with 1/2-inch OD tubing and 1/2-inch NPT ported components in compressed air and pneumatic plumbing systems meeting SAE J844 and related air brake tubing standards.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake system regulations and applicable SAE standards. Depressurize the system completely and confirm zero pressure before removing or installing any fitting. Ensure the 1/2-inch OD tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect ports. Apply thread sealant compatible with compressed air service to the NPT thread per shop practice and applicable codes.
