Parker 171CA-4-2 Compression Male Run Tee Brass 1400 Psi

Product Description

The PARKER 171CA-4-2 is a brass compression tube male run tee designed for fluid and gas line connections in plumbing, HVAC, and instrumentation applications. It features a Compression x MNPT x Compression end configuration with a 1/8-27 NPTF thread on the male branch port. The fitting is rated to 1400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. Constructed from brass, it provides reliable corrosion resistance in wet and pneumatic service environments. Licensed plumbers, HVAC technicians, and instrumentation mechanics typically install this fitting in tubing runs where a threaded branch takeoff is required without interrupting the main compression line.

This fitting suits residential and light commercial applications where copper or compatible soft tubing connects to threaded pipe or equipment ports. The male run tee orientation keeps the main compression run inline while the MNPT branch connects to valves, gauges, sensors, or equipment fittings. It is well suited to refrigeration lines, pneumatic control circuits, fuel gas distribution panels, and hydraulic instrument loops that operate within the rated pressure and temperature envelope.

Key Features

• Compression x MNPT x Compression end connections keep the main tubing run uninterrupted
• 1/8-27 NPTF thread provides a pressure-tight mechanical seal on the branch port
• 1400 psi maximum working pressure suits demanding pneumatic and hydraulic service
• Rated from -65 degrees F to 250 degrees F for broad temperature service range
• Brass construction offers corrosion resistance in wet, refrigerant, and fuel service environments

Compatibility

Designed as an OEM-style compression tube fitting for use in tubing systems requiring a male NPT branch outlet; consult Parker documentation for compatible tubing outside diameter and wall thickness specifications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or instrumentation mechanic familiar with compression fitting assembly and applicable codes such as the IPC or IFGC. Depressurize and isolate the line completely before disassembly or installation. Compression fittings require the tubing end to be cut square and deburred before inserting into the fitting body; do not over-tighten, as brass compression fittings can crack if excessively torqued. Apply thread sealant or PTFE tape to the NPTF male thread branch per the applicable system requirements.
