Parker 170CA-6-4 Compression Female Elbow 1/4-18 Fnpt

Product Description

The PARKER 170CA-6-4 is a brass compression tube female elbow fitting designed to connect a compression tube end to a female NPT port at a 90-degree angle. Rated for a maximum working pressure of 1000 psi and a temperature range of -65 degrees F to 250 degrees F, this fitting is built for demanding fluid and pneumatic systems. The 1/4-18 NPTF thread ensures a pressure-tight mechanical seal without relying solely on thread sealant. Plumbers, HVAC technicians, and fluid-system installers use this fitting to transition from tubing runs to threaded female ports on valves, manifolds, and equipment bodies.

This elbow is suited for residential and light commercial applications where a 90-degree direction change is needed between a compression tube line and a fixed female NPT port. Common install scenarios include refrigeration lines, pneumatic control tubing, instrumentation piping, and hydraulic distribution systems. The brass construction makes it compatible with a wide range of compatible media and provides corrosion resistance in typical service environments.

Key Features

• 90-degree elbow configuration for direction changes in tight spaces
• Compression x FNPT end connections for tool-free tube insertion on one end
• 1/4-18 NPTF thread standard for a pressure-tight mechanical seal
• 1000 psi maximum working pressure for demanding fluid and pneumatic service
• Wide temperature range: -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance and durability

Compatibility

Designed as an OEM-style compression tube female elbow fitting for fluid, pneumatic, and instrumentation systems requiring a 1/4-18 NPTF female port connection with a compression tube inlet.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified fluid-systems technician. Shut off and depressurize the system fully before removing or installing any fittings. Ensure the compression tube end is cut cleanly and squarely before seating it into the fitting. NPTF threads are designed for a dry-seal mechanical fit, but consult applicable IPC or system specifications for thread sealant requirements in your jurisdiction.
