Parker 171CA-3-2 Compression Male Run Tee Brass

Product Description

The PARKER 171CA-3-2 is a brass compression tube male run tee designed for use in instrumentation, fluid control, and pneumatic or hydraulic tubing systems. It provides a three-port inline connection with compression fittings on both run ends and a male NPTF threaded branch port. Rated to 1900 psi maximum working pressure, the fitting handles temperatures from -65 degrees F to 250 degrees F. Constructed from brass, it resists corrosion and is well suited for use with copper or compatible soft tubing. Licensed HVAC, plumbing, and instrumentation technicians install this fitting in applications requiring a secure, leak-resistant tube-to-pipe transition.

This fitting is used in residential and light commercial HVAC systems, refrigeration lines, compressed air distribution, hydraulic circuits, and instrumentation tubing runs where a branch connection to a male NPT port is needed inline. The compression-by-MNPT-by-compression configuration allows the technician to tap off a main tubing run to a threaded component such as a valve, gauge, or manifold without interrupting the primary flow path. It is appropriate for both new installations and retrofit service work on existing tubing assemblies.

Key Features

• Brass construction provides corrosion resistance and durability in fluid and pneumatic systems
• 1900 psi maximum working pressure rating suitable for demanding service environments
• Wide temperature range: -65 degrees F to 250 degrees F
• 1/8-27 NPTF thread standard ensures pressure-tight engagement at the male branch port
• Compression x MNPT x Compression end configuration allows inline branch connection without cutting the primary tubing run
• Single-piece package quantity allows for precise inventory control and one-off service calls

Compatibility

Designed as an OEM-style replacement or direct-use fitting for tubing systems requiring a compression-to-MNPT inline tee connection with 1/8-27 NPTF thread specifications.

Installation Notes

Installation of compression fittings should be performed by a qualified plumbing, HVAC, or instrumentation technician. Always depressurize and isolate the tubing circuit before disassembly or installation. Ensure tubing ends are cut cleanly and deburred before seating the compression ferrule to achieve a leak-free connection. NPTF threads are self-sealing by design, but verify thread engagement and pressure-test the assembly after installation before returning the system to service.
