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

Product Description

The PARKER 169HD-4-4 is a brass compression tube male elbow fitting designed to connect 1/4-inch compression tubing to a male NPT threaded port at a 90-degree angle. It transitions a compression tube connection to an MNPT end, making it a go-to fitting for refrigerant lines, instrumentation tubing, and pneumatic control circuits. Rated to 2100 psi maximum working pressure and suitable for service from -65 degrees F to 121 degrees C (250 degrees F), this fitting handles demanding pressure and temperature conditions found in HVAC, refrigeration, and industrial fluid systems. Licensed plumbers, HVAC technicians, and pipefitters install this fitting where a direction change is needed at a threaded port connection.

This male elbow is suited for residential and light commercial HVAC systems, refrigeration equipment, pneumatic control lines, and hydraulic instrumentation circuits. The compression-by-MNPT configuration allows a technician to connect copper or compatible compression tubing directly to any standard 1/4-inch male NPT port. Its compact elbow geometry is useful in tight equipment cabinets or panel enclosures where straight fittings cannot route properly. The 0.1-pound weight reflects the compact single-piece brass construction typical of this fitting class.

Key Features

• Brass construction for corrosion resistance and compatibility with common refrigerant and pneumatic media
• 2100 psi maximum working pressure rating for high-pressure system applications
• Wide service temperature range: -65 degrees F minimum to 121 degrees C maximum
• 1/4-inch thread size with MPT thread standard on the male NPT end
• Compression x MNPT end connections eliminate the need for soldering or flaring at the tube end
• Sold individually, no minimum order quantity beyond one unit

Compatibility

Designed as an OEM-style replacement or direct-install compression tube male elbow for systems using 1/4-inch compression tube connections terminating at a standard male NPT threaded port.

Installation Notes

Installation is typically performed by a licensed HVAC technician, refrigeration mechanic, or pipefitter. Shut off and depressurize the system fully before disassembling any existing fittings. Hand-tighten the MNPT end into the receiving port, then wrench-tighten per standard practice for brass NPT fittings, taking care not to overtighten and crack the fitting body. Ensure the compression sleeve and nut are properly seated on the tubing before torquing the compression end to achieve a leak-free connection.
