Parker 170CA-2-2 Compression Female Elbow 1/8-27 Fnpt

Product Description

The PARKER 170CA-2-2 is a brass compression tube female elbow fitting designed to connect tubing to female NPT-threaded ports at a 90-degree angle. It features a compression-style tube end on one side and a 1/8-27 FNPT threaded end on the other, creating a reliable, leak-resistant joint without soldering. Rated to 2800 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this fitting suits demanding fluid and pneumatic line applications. It is installed by licensed plumbers, HVAC technicians, and instrumentation mechanics working on refrigeration, hydraulic, or compressed-air systems.

The 170CA-2-2 is suited for residential and commercial installations where 1/8-inch OD tubing must transition to a female NPT port. Typical applications include instrument tubing connections, control line assemblies, and small-bore fluid circuits in HVAC equipment, pneumatic panels, and process control systems. The NPTF thread standard provides a pressure-tight seal at the threaded joint without relying solely on a separate sealant, though thread sealant is generally applied per system requirements.

Key Features

• Compression x FNPT end connections allow tool-made, solder-free tube-to-port transitions
• Brass construction resists corrosion in water, air, and many fluid service applications
• 2800 psi maximum working pressure supports high-pressure pneumatic and hydraulic lines
• Wide service temperature range from -65 degrees F to 250 degrees F
• 1/8-27 NPTF thread standard provides a pressure-tight threaded connection
• Compact elbow geometry eases routing in tight or congested panel spaces

Compatibility

Designed as an OEM-style compression fitting for use with 1/8-inch OD tubing and 1/8-27 female NPT-threaded ports across residential and commercial fluid, pneumatic, and instrumentation systems.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or instrumentation mechanic. Depressurize and isolate the system completely before removing or installing any fittings. Insert tubing to the full depth of the compression fitting body before tightening the compression nut, and do not overtighten, as brass fittings are susceptible to thread damage. Apply an appropriate thread sealant or PTFE tape to the NPTF threads per the system manufacturer and applicable code requirements.
