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

Product Description

The PARKER 170HD-2-2 is a brass compression tube female elbow designed for making a 90-degree directional change in tubing runs with a threaded female port connection. It features a compression inlet on one end and a 1/8 inch female NPT (FNPT) port on the other, allowing a secure transition between compression tubing and threaded pipe or fittings. Rated to 4300 psi maximum working pressure, this fitting is built for demanding hydraulic, pneumatic, instrumentation, and fluid control applications. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this type of fitting in both residential and light commercial systems.

This fitting is suited for use in refrigeration lines, compressed air systems, hydraulic circuits, and instrumentation tubing assemblies where a reliable 90-degree turn and a threaded port connection are required. The compression-by-FNPT configuration makes it a practical choice when connecting tubing to a threaded valve body, manifold, or instrument port. It is commonly found in control panel plumbing, pressure sensing lines, and equipment with tight routing constraints that demand a low-profile elbow rather than a union and separate elbow.

Key Features

• Brass construction for corrosion resistance and durability in fluid and gas service
• Compression x FNPT end connections for tool-friendly installation without special equipment
• 1/8 inch female NPT thread conforms to FPT standard for broad fitting compatibility
• 4300 psi maximum working pressure rating supports high-pressure pneumatic and hydraulic service
• 90-degree elbow geometry allows directional routing in confined spaces

Compatibility

Designed as an OEM-style compression tube female elbow for systems requiring a 1/8 inch FNPT connection with a compression tube inlet, typical in pneumatic, hydraulic, and instrumentation plumbing assemblies.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or instrumentation mechanic following applicable codes such as the IPC or system manufacturer guidelines. Depressurize and isolate the line completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the tubing, then apply the additional turns specified for the tubing material and wall thickness per standard compression fitting practice. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
