Parker 170HD-4-4 Compression Female Elbow 1/4 in Brass

Product Description

The PARKER 170HD-4-4 is a brass compression tube female elbow fitting designed for use in fluid and gas distribution systems. It transitions between a compression tube connection and a female NPT (FNPT) threaded port at a 90-degree angle, allowing direction changes in tubing runs without additional adapters. Rated to 2100 psi maximum working pressure, this fitting is built for demanding service conditions. The brass construction resists corrosion and provides reliable sealing performance. It is commonly installed by licensed plumbers, HVAC technicians, and instrumentation technicians working on refrigeration lines, instrumentation tubing, or hydraulic and pneumatic plumbing circuits.

This fitting is suited for residential and commercial applications where a tubing run must connect to a female NPT threaded port at a right angle. Typical install scenarios include instrument panel connections, control line plumbing, compressed air distribution, and refrigeration service applications. The 1/4 inch thread size is a common dimension across light commercial and residential trade work, making this elbow a standard-stock item for service vans and job site inventory.

Key Features

• 90-degree elbow routes tubing in tight spaces without bending or kinking
• Compression x FNPT end connections allow direct attachment to female NPT threaded ports
• 2100 psi maximum working pressure rating for high-pressure service environments
• Brass construction provides corrosion resistance and long service life
• 1/4 inch thread size fits standard trade plumbing and instrumentation applications

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4 inch compression tube connections terminating at female NPT threaded ports in plumbing, HVAC, instrumentation, and pneumatic applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and depressurize the line completely before removing or installing compression fittings. Use appropriate tube cutters to ensure a clean, square tube end before seating the compression sleeve. Do not overtighten compression fittings; follow the fitting manufacturer's standard hand-tight-plus-turn procedure appropriate for the tube material and system pressure.
