Parker 172PTC-4-4 Swivel Male Branch Tee 1/4 in Od Npt

Product Description

The PARKER 172PTC-4-4 is a push-to-connect swivel male branch tee fitting designed for use in compressed air brake and pneumatic tubing systems. Constructed from brass, it accepts 1/4-inch OD tubing on the tube ports and features a 1/4-inch NPT male thread on the branch. The fitting is rated to 250 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F. The push-to-connect ends allow fast, tool-free tube insertion while the swivel male thread simplifies alignment during installation. This fitting carries D.O.T. designation as an air brake fitting and conforms to FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844 standards. Licensed HVAC technicians, fleet mechanics, and plumbing professionals working on air-operated systems typically specify this part.

The 172PTC-4-4 is suited for residential and commercial pneumatic plumbing, air brake lines, and compressed air distribution runs where a tee connection is needed between 1/4-inch OD tubing and a male NPT port. The swivel male branch allows the fitting to be threaded into a manifold, valve body, or component port and then rotated for tube alignment without disturbing the thread seal. Its brass construction makes it appropriate for dry air and other compatible media in moderate-pressure service. This fitting ships as a single unit and is commonly used wherever a branch takeoff is required in a D.O.T.-compliant air brake circuit.

Key Features

• Brass construction provides corrosion resistance in compressed air service
• 250 psi maximum working pressure rating supports standard air brake and pneumatic system demands
• Wide temperature range of -40 degrees F to 200 degrees F suits mobile and stationary applications
• D.O.T. air brake fitting designation; compliant with FMVSS 571.106, SAE J2494, SAE J2494-3, and SAE J844

Compatibility

Designed as an OEM-style D.O.T. air brake push-to-connect fitting for pneumatic and compressed air plumbing circuits using 1/4-inch OD tubing with 1/4-inch NPT male thread connections.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air systems and applicable D.O.T. air brake regulations. Depressurize and bleed down the air system completely before disconnecting or installing any fittings. Ensure the NPT male thread is wrapped with compatible thread sealant tape or compound before torquing into the receiving port. Verify tube ends are cut cleanly and squarely and that tubing is fully seated in the push-to-connect collet before returning the system to service.
