Parker 172HD-4-4 Brass Compression Male Branch Tee 1/4 in

Product Description

The PARKER 172HD-4-4 is a brass male branch tee fitting designed to split or branch a compression tube line while transitioning to a male NPT threaded port. It features three end connections: two compression ports and one 1/4 inch MNPT port. Constructed from brass, it is rated for working pressures up to 2100 psi, making it suitable for demanding fluid and gas line applications. Licensed plumbers, HVAC technicians, and refrigeration mechanics typically install this fitting in instrument tubing, control line, and distribution manifold assemblies where a branch point with a threaded takeoff is required.

This fitting is used in residential and commercial applications where a compression tube run must branch off to a threaded connection point. Common install scenarios include instrument air lines, oil or fuel distribution systems, and HVAC refrigerant or control tubing assemblies. The two compression ends accept tubing directly without soldering or flaring, while the MNPT end connects to a standard male NPT threaded port on a valve, gauge, or manifold body.

Key Features

• Brass construction for corrosion resistance and long service life in fluid and gas systems
• Dual compression ports allow tool-free tubing connections without soldering or flaring
• 1/4 inch MNPT port provides a standard threaded takeoff for valves, gauges, or manifolds
• Rated to 2100 psi maximum working pressure for high-pressure line applications
• Compact male branch tee geometry keeps plumbing layouts tight and organized

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring a male NPT branch outlet with 1/4 inch thread size.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or refrigeration mechanics familiar with compression fittings and NPT thread practices. Shut off and depressurize the line completely before disassembling or installing any fitting. Ensure tubing is cut cleanly and squarely and that the compression sleeve seats properly before tightening the compression nut. Apply appropriate thread sealant to the MNPT port in accordance with the applicable plumbing or mechanical code, such as the IPC or IFGC.
