Parker 169HD-5-4 Compression Male Elbow 1/4 in Brass

Product Description

The PARKER 169HD-5-4 is a brass compression tube male elbow fitting designed for use in fluid and gas distribution systems where a 90-degree directional change is required. It connects a compression tube end to a male NPT threaded port, providing a reliable, leak-resistant joint without soldering or brazing. Rated to 1800 psi maximum working pressure, this fitting is built for demanding service environments. The all-brass construction offers corrosion resistance suitable for air, water, and compatible fluid lines. Licensed plumbers, HVAC technicians, and instrumentation technicians are the primary installers of this type of fitting.

This fitting is used in residential and commercial applications where tubing must terminate or transition at a male pipe thread port. Typical installations include refrigeration lines, compressed air systems, hydraulic instrumentation tubing, and plumbing supply connections. The compression-by-MNPT configuration makes it well suited for connecting copper or compatible soft tubing to valves, manifolds, or equipment ports with 1/4-inch male NPT threads. The 90-degree elbow orientation helps route tubing cleanly in tight spaces without bending the tube sharply.

Key Features

• Compression x MNPT end connections allow tool-friendly tube-to-thread assembly without soldering
• 1800 psi maximum working pressure rating for demanding fluid and gas service
• All-brass construction for corrosion resistance and long service life
• 1/4-inch thread size with MPT thread standard for broad port compatibility
• 90-degree male elbow geometry simplifies tubing routing in confined installations

Compatibility

Designed as an OEM-style compression fitting replacement for systems using 1/4-inch male NPT threaded ports with compression tube connections in HVAC, plumbing, refrigeration, and instrumentation applications.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation mechanics following applicable IPC and system manufacturer guidelines. Shut off and depressurize the line completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice — do not overtighten, as this can crack the ferrule or distort the tube end. Verify there are no leaks under pressure before returning the system to service.
