Parker 170CA-4-4 Compression Female Elbow 1/4-18 Fnpt

Product Description

The PARKER 170CA-4-4 is a brass compression tube female elbow fitting designed to connect a compression tube line to a female NPT port at a 90-degree angle. Built from brass, this fitting handles a maximum working pressure of 1400 psi and operates across a temperature range of -65 degrees F to 250 degrees F. The end connections are compression on one side and FNPT on the other, with a 1/4-18 thread size conforming to NPTF standards. Plumbers, HVAC technicians, and instrumentation mechanics install this fitting wherever a tube-to-pipe transition is needed at a right angle in fluid or gas distribution systems.

This fitting is suited for residential and light commercial plumbing, refrigeration, pneumatic, and hydraulic instrumentation applications. The compression-by-FNPT configuration makes it a practical choice when connecting copper or brass tubing to a threaded female port on valves, manifolds, or equipment panels. Its temperature and pressure ratings accommodate a wide range of working fluids and gases encountered in trade service work.

Key Features

• Brass construction for corrosion resistance and durability in fluid and gas service
• Maximum working pressure of 1400 psi for demanding system requirements
• Wide temperature range: -65 degrees F to 250 degrees F
• Compression x FNPT end connections enable tube-to-pipe transitions at 90 degrees
• 1/4-18 thread size meets NPTF standards for reliable sealing

Compatibility

Designed as an OEM-style replacement or service fitting for systems requiring a compression tube to female NPT elbow connection in 1/4-18 thread size.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians. Shut off system pressure and relieve any residual pressure in the line before removing or installing compression fittings. Ensure the compression ferrule and nut are properly seated before tightening; do not overtighten, as this can deform the ferrule or damage the fitting. Follow applicable IPC or local plumbing code requirements for fitting selection and installation in pressurized systems.
