Parker 172C-4-4 Compression Male Branch Tee 1/4-18

Product Description

The PARKER 172C-4-4 is a brass compression tube male branch tee designed for use in fluid and pneumatic line assemblies requiring a three-way branch connection. It features compression fittings on two ports and a male NPT connection on the branch, making it suitable for splitting or routing tubing runs while maintaining a secure, leak-resistant seal. Rated to 300 psi maximum working pressure and built to SAE J-512 standards, this fitting handles a wide temperature range from -65 degrees F to 250 degrees F. Plumbers, HVAC technicians, and fluid-system installers use this fitting in both service and OEM assembly applications.

This fitting is commonly used in residential and light commercial plumbing, refrigeration, and instrumentation applications where a branch tee connection is needed in a compression tube system. The 1/4-18 NPTF thread on the male branch port provides a pressure-tight mechanical seal without the need for sealant tape in many installations. Its brass construction resists corrosion and suits use with water, air, and a range of compatible process fluids.

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube systems requiring a male branch tee with 1/4-18 NPTF male thread and SAE J-512 compliant compression connections.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Shut off and depressurize the system completely before removing or installing any fittings. Ensure tubing ends are cut square, deburred, and fully seated against the fitting shoulder before tightening the compression nut. Consult applicable plumbing codes such as the IPC for approved applications and materials in your jurisdiction.
