Parker 171CA-6-4 Compression Male Run Tee Brass 1000 Psi

Product Description

The PARKER 171CA-6-4 is a brass compression tube male run tee designed for use in fluid and pneumatic line assemblies where a branch connection must be made along a tube run while maintaining a threaded port for a male NPT fitting. Constructed from brass, this fitting handles working pressures up to 1000 psi and a temperature range of -65 to 250 degrees F. The end connections are Compression x MNPT x Compression, with a 1/4-18 thread size conforming to the NPTF standard. Licensed plumbers, HVAC technicians, and instrumentation technicians install this fitting in copper and compatible soft-metal tubing systems.

This fitting is suited for residential and commercial plumbing, refrigeration, and pneumatic control line applications where a tee connection requires one branch to terminate at a male pipe thread port. The run-through compression ends allow the main tube line to pass continuously while the MNPT branch connects to valves, gauges, or manifolds. It is commonly found in HVAC refrigerant line sets, compressed air distribution, and hydraulic control circuits that operate within its rated pressure and temperature limits.

Key Features

• Compression x MNPT x Compression end connections allow inline tee with a threaded branch port
• Brass construction provides corrosion resistance and compatibility with copper tubing systems
• Rated to 1000 psi maximum working pressure for use in demanding pneumatic and fluid systems
• Wide temperature range of -65 to 250 degrees F supports refrigeration and high-temperature service
• 1/4-18 thread size per NPTF standard ensures pressure-tight threaded connections without additional sealant on dry-seal threads

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems using 1/4-18 NPTF threaded branch connections in plumbing, HVAC, and pneumatic applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation technician. Depressurize and isolate the line fully before disassembling any existing fittings or inserting this tee into a tube run. Compression fittings require proper tube squareness and deburring before seating the ferrule to achieve a leak-free connection. Follow applicable codes including IPC and IFGC for fluid and gas piping applications.
