Parker 170CA-4-2 Compression Female Elbow 1/8-27 Fnpt

Product Description

The PARKER 170CA-4-2 is a brass compression tube female elbow fitting designed to connect compression tubing to a female NPT port at a 90-degree angle. Rated to 1400 psi maximum working pressure, it handles a temperature range from -65 degrees F to 250 degrees F, making it suitable for demanding fluid and gas line applications. The fitting features a 1/8-27 NPTF thread on the female end with a compression connection on the tube end. It is installed by licensed plumbers, HVAC technicians, and instrumentation technicians working on refrigerant, pneumatic, hydraulic, or fluid-transfer systems.

This fitting is suited for use in residential, commercial, and light industrial applications where a directional change is needed between a compression tube line and a female NPT port. Common install scenarios include instrument tubing runs, refrigerant piping, compressed air systems, and hydraulic control lines. The 90-degree elbow configuration reduces stress on tubing at direction changes and keeps installations compact in tight spaces.
