Parker 172CA-12-12 Compression Male Branch Tee Brass

Product Description

The PARKER 172CA-12-12 is a brass male branch tee fitting designed for compression tube systems requiring a threaded branch outlet. It connects two compression tube ends with a 3/4-14 NPTF male pipe thread on the branch port. Constructed from brass, this fitting handles working pressures up to 550 psi and temperatures ranging from -65 degrees F to 250 degrees F. It is used in hydraulic, pneumatic, and fluid distribution lines where a reliable inline branch connection is needed. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during system assembly or service.

This fitting is suited for residential and commercial plumbing, refrigeration, and instrumentation applications where a compression-to-compression run with a male NPT branch outlet is required. The NPTF thread standard provides a pressure-tight mechanical seal without relying on sealant alone, making it appropriate for moderate-pressure fluid and gas lines. It is a single-piece, no-weld solution for branch connections in copper or compatible tubing systems.

Key Features

• Brass construction for corrosion resistance and durability in fluid service
• End connections: Compression x Compression x MNPT for versatile inline branch routing
• 3/4-14 NPTF thread standard for pressure-tight branch port seal
• Rated to 550 psi maximum working pressure
• Wide temperature range: -65 degrees F to 250 degrees F
• No-weld installation reduces labor time during assembly or repair

Compatibility

Designed as an OEM-style replacement or direct-install brass compression male branch tee for systems using 3/4-14 NPTF threaded branch outlets with compression tube run connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC code requirements. Shut off and depressurize the system completely before removing or installing any fitting. Hand-tighten the compression nuts first, then tighten to the appropriate turn count per the tube and fitting manufacturer guidance — do not overtighten, as brass compression fittings can be deformed. Apply thread sealant or PTFE tape to the NPTF branch port threads as required by system media and local code.
