Parker 169PS-4-2 Compression Swivel Elbow 1/4 in Tube 1/8 Mnpt

Product Description

The PARKER 169PS-4-2 is a brass compression tube swivel elbow designed to connect 1/4-inch OD tubing to a 1/8-inch male NPT port at a 90-degree angle. The swivel design allows the elbow to rotate during and after installation, reducing torsional stress on tubing and simplifying routing in tight spaces. Constructed from brass, this fitting offers reliable corrosion resistance and durability in both pneumatic and fluid system applications. It is commonly installed by licensed plumbers, HVAC technicians, and instrumentation mechanics working on compressed air, refrigeration lines, fuel systems, and process fluid circuits.

This swivel elbow is suited for residential and light commercial applications where 1/4-inch OD tubing must transition to a 1/8-inch MNPT threaded port. Typical installation scenarios include control line connections on HVAC equipment, pneumatic instrument tubing runs, and small-bore plumbing assemblies where a fixed elbow would place excessive strain on the tubing or restrict routing flexibility. The compression end requires no flaring or soldering, making it well suited for field service and quick-turnaround repairs.

Key Features

• Swivel design allows rotation after assembly to reduce tubing stress and simplify alignment
• Compression x MNPT end connections eliminate the need for flaring or soldering
• 1/4-inch tube OD compression end accepts standard soft or semi-rigid tubing
• 1/8-inch male NPT thread provides a standard tapered pipe thread connection
• Brass construction provides corrosion resistance for air, water, and compatible fluid service

Compatibility

Designed as an OEM-style replacement fitting for systems using 1/4-inch OD compression tubing with 1/8-inch MNPT threaded ports in HVAC, plumbing, and pneumatic applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic following applicable local codes. Depressurize and isolate the system completely before removing or installing any compression fitting. Hand-tighten the compression nut first, then advance with a wrench only enough to seat the ferrule without over-tightening, which can crack the ferrule or deform the tubing. Apply thread sealant or PTFE tape to the NPT threads in accordance with the system fluid compatibility requirements.
