Parker 172C-6-2 Compression Male Branch Tee Brass 200 Psi

Product Description

The PARKER 172C-6-2 is a brass male branch tee fitting designed to split or branch a compression tube line while transitioning to a male NPT connection. It features two compression ends and one male NPT (MNPT) port, following the NPTF thread standard for pressure-tight sealing without sealant tape on the threaded connection. The fitting is rated to 200 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and pneumatic line applications. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this type of fitting in control line, instrument air, and process fluid assemblies.

This fitting is used in residential and light commercial applications where a compression tube branch must connect to a male NPT port on a valve, manifold, or instrument. Typical install scenarios include control line tees in HVAC refrigeration circuits, pneumatic instrument tubing, and low-pressure fluid distribution headers. The brass construction provides corrosion resistance in air, water, and many common refrigerant or oil-mist environments. The 1/8-27 thread size is standard for small-bore NPT fittings found throughout HVAC and plumbing systems.

Key Features

• Two compression tube ends and one 1/8-27 MNPT port for branch tee configuration
• NPTF thread standard provides a pressure-tight mechanical seal on the threaded connection
• Rated to 200 psi maximum working pressure
• Operating temperature range of -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance in fluid and pneumatic service

Compatibility

Designed as an OEM-style compression branch tee for use in small-bore tubing assemblies with 1/8-27 NPTF male threaded ports in HVAC, plumbing, and light industrial pneumatic or fluid control systems.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation mechanic. Depressurize and isolate the line fully before disassembling any compression fitting. Compression nuts should be tightened hand-snug and then a fixed number of turns per the tube OD and fitting manufacturer guidelines — do not overtighten brass compression fittings as this can crack the ferrule. Verify thread engagement and pressure-test the assembly before returning the system to service.
