Parker 169HD-4-2 Compression Male Elbow 1/8 in Mnpt Brass

Product Description

The PARKER 169HD-4-2 is a brass compression tube male elbow fitting designed to create a 90-degree directional change in a compression tubing line while transitioning to a male NPT threaded port. It connects a compression tube end to a 1/8 inch MNPT fitting, making it a common choice in instrumentation, HVAC control lines, refrigeration sensing lines, and light fluid or gas distribution systems. The fitting is rated to 2100 psi maximum working pressure and handles temperatures from -65 degrees F to 121 degrees C, making it suitable for a wide range of service conditions. Plumbers, HVAC technicians, and instrumentation mechanics install this fitting when a compact elbow transition is needed between tubing and a threaded port.

This fitting is used in residential and commercial applications where a compression tube must connect at a right angle to a male NPT threaded port. Typical install scenarios include control line connections on HVAC equipment, gas appliance sensing lines, pneumatic control systems, and hydraulic instrumentation circuits. The 1/8 inch thread size fits standard 1/8 MNPT ports commonly found on pressure gauges, solenoid valves, and control valve bodies. Its brass construction provides corrosion resistance for use with water, air, and many non-corrosive fluids and gases.

Key Features

• Brass construction offers corrosion resistance for water, air, and compatible fluid service
• Compression x MNPT end connections allow tool-free tube insertion with a threaded port transition
• 2100 psi maximum working pressure rated for demanding control and instrumentation service
• Wide temperature range from -65 degrees F to 249 degrees F supports varied operating environments
• 1/8 inch MNPT thread fits standard small-port gauge and valve connections
• Compact male elbow geometry reduces space requirements at 90-degree direction changes

Compatibility

Designed as an OEM-style compression tube male elbow for use with standard compression tubing and 1/8 inch MNPT threaded ports in HVAC, plumbing, and instrumentation applications.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or instrumentation mechanics. Shut off and depressurize the system completely before disassembly or installation. Apply thread sealant tape or compound to the MNPT threads in accordance with the applicable plumbing or mechanical code. Do not overtighten the compression nut, as brass fittings can be damaged by excessive torque beyond hand-tight plus the standard fractional turn recommended by the tubing manufacturer.
