Parker 170HD-6-4 Compression Female Elbow 1/4 in Fnpt

Product Description

The PARKER 170HD-6-4 is a brass compression tube female elbow fitting designed for connecting tubing to female NPT threaded ports at a 90-degree angle. It accepts a compression tube connection on one end and a 1/4 inch FNPT threaded connection on the other, making it a direct, leak-resistant transition between tube and pipe systems. Rated to 1500 psi maximum working pressure, this fitting is built for demanding fluid and pneumatic service applications. Licensed plumbers, HVAC technicians, and industrial pipefitters commonly install this fitting in refrigeration, instrumentation, and pneumatic control line work.

This elbow fitting is suited for residential and commercial applications where a right-angle transition is needed between a compression tube line and a female NPT port. Typical install scenarios include instrument tubing connections, control line routing, and HVAC refrigerant or pneumatic service lines where a directional change is required without sacrificing pressure integrity. The brass construction provides good corrosion resistance in water, air, and many fluid media commonly found in plumbing and HVAC systems.

Key Features

• Compression x FNPT end connections for tube-to-pipe transitions at a 90-degree angle
• 1/4 inch thread size conforming to FPT standard
• 1500 psi maximum working pressure rating
• Brass material for corrosion resistance and durability
• Female elbow configuration allows directional routing in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube and female NPT port connections in plumbing, HVAC, pneumatic, and fluid instrumentation systems.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system completely before removing or installing any compression fitting. Ensure the tubing end is cut cleanly and squarely and that the compression ferrule is seated properly before tightening the nut. Follow applicable plumbing and mechanical codes, including IPC and ASME B31 guidelines, for pressure system connections.
