Parker 171CA-2-2 Brass Compression Male Run Tee

Product Description

The PARKER 171CA-2-2 is a brass compression male run tee designed for tube-to-pipe branching connections in fluid and pneumatic systems. It features compression fittings on both run ends and a male NPTF threaded branch port, allowing an inline tube run to tap off to a threaded pipe connection without cutting the main line. Rated to 2800 psi maximum working pressure, this fitting handles demanding service conditions across a wide temperature range of -65 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this fitting where a compact, leak-resistant tube branch is required in brass-compatible systems.

This fitting suits residential and light commercial applications where copper or compatible soft tubing must branch to a male NPT port. Typical install scenarios include refrigeration line sets, pneumatic control circuits, fuel gas instrumentation tubing, and hydraulic sampling lines. The compression-by-MNPT-by-compression configuration makes it well suited for tight spaces where a soldered or flared tee would be impractical. Its NPTF thread standard provides a pressure-tight mechanical seal without relying solely on thread sealant.

Key Features

• Compression x MNPT x Compression end configuration for inline tube branching to a threaded port
• Rated to 2800 psi maximum working pressure for high-pressure service
• Operating temperature range: -65 degrees F to 250 degrees F
• NPTF thread standard for a dry-seal pressure-tight connection
• Brass construction for corrosion resistance and compatibility with common tube materials
• 1/8-27 thread size fits standard NPT instrument and control ports

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring a male run tee with NPTF threaded branch connections in brass-compatible fluid or pneumatic circuits.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic familiar with compression fitting assembly. Depressurize and drain the system fully before disassembly or fitting installation. Seat the compression ferrule squarely on the tube and tighten the compression nut to a firm, snug fit — do not over-tighten, as brass ferrules can deform. Apply appropriate thread sealant or PTFE tape to the NPTF male threads per the applicable plumbing or mechanical code before making up the threaded joint.
