PARKER Push-Fit Tee Fitting: 3/8 in OD x 1/4 in Pipe Fitting Size

The Parker Push-Fit Tee Fitting is used in compressed air and pneumatic systems to branch a 3/8 in OD tube line into a 1/4 in MNPT threaded connection. It is common in truck air brakes, industrial automation, and plant air-distribution networks where a reliable, leak-free brass fitting is required.

The Parker VS171PTCNS-6-4 is a brass air brake tee fitting with a 3/8 in OD push-to-connect x 3/8 in OD push-to-connect x 1/4 in MNPT configuration. It includes Vibra-Seal thread sealant pre-applied to the male NPT threads for vibration-resistant sealing without additional tape or paste.

To install a Parker push-to-connect tee fitting, cut the tube square, deburr, and push it fully into the collet until it stops. For the MNPT end, apply thread sealant (Vibra-Seal is pre-applied on this model) and tighten to the port. Ensure the tube is fully seated and pull back slightly to confirm lock. No tools are needed for the push-connect ports.
