Parker 170HD-6-2 Compression Female Elbow 1/8 in Fnpt

Product Description

The PARKER 170HD-6-2 is a brass compression tube female elbow fitting designed to create a 90-degree directional change in tubing runs while transitioning to a female NPT threaded port. The fitting uses a compression-style tube connection on one end and a 1/8 inch FNPT connection on the other, rated to a maximum working pressure of 1500 psi. This type of fitting is commonly installed by plumbers, HVAC technicians, and refrigeration mechanics in instrument, control, and fluid-transfer lines where a secure, leak-resistant tube-to-pipe connection is required at a right-angle junction.

The 170HD-6-2 is suited for residential and light commercial applications involving copper, aluminum, or compatible plastic tubing in gas, air, hydraulic, and instrumentation service lines. The compression end allows tool-assisted tube engagement without soldering or brazing, making it practical for retrofit and service work in confined spaces. Typical installation scenarios include control-line connections on HVAC equipment, pneumatic instrument tubing, and small-bore fluid distribution systems.

Key Features

• Compression x FNPT end connections enable tube-to-pipe transitions at a 90-degree angle
• 1/8 inch female NPT thread matches standard instrument and control-line port sizes
• Brass construction provides corrosion resistance and durability in fluid and gas service
• Rated to 1500 psi maximum working pressure for demanding service environments
• No soldering or brazing required on the compression end — mechanical connection only

Compatibility

Designed as an OEM-style compression tube female elbow for use in instrument, control, and fluid-transfer tubing systems requiring a 1/8 inch FNPT port connection.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter. Shut off system pressure and depressurize the line completely before removing or installing any compression fitting. Hand-tighten the compression nut before applying a final turn with a wrench to seat the ferrule against the tube; do not overtighten. Apply thread sealant to the FNPT end per the applicable system requirements and local plumbing or mechanical code.
