Parker 170CA-6-6 Compression Female Elbow 3/8-18

Product Description

The PARKER 170CA-6-6 is a brass compression tube female elbow designed to connect tubing to female NPT-threaded ports at a 90-degree angle. It uses a compression fitting on one end and an FNPT connection on the other, making it a standard choice for fluid and gas line assemblies in HVAC, refrigeration, and plumbing applications. The fitting handles a maximum working pressure of 1000 psi and is rated for temperatures from -65 degrees F to 250 degrees F. Brass construction provides corrosion resistance and reliable sealing across a range of compatible media. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting in both residential and light commercial systems.

This elbow is suited for applications requiring a directional change from a compression tube run to a female NPT port. Common install scenarios include connecting copper or compatible tubing to valves, gauges, manifolds, or equipment ports where an inline connection is not practical. The 3/8-18 NPTF thread standard ensures a pressure-tight mechanical seal at the threaded end. It is appropriate for use in refrigerant piping, pneumatic lines, and hydraulic circuits within the rated temperature and pressure range.

Key Features

• 90-degree elbow routes tubing in tight or angled installations
• Compression x FNPT end connections for tool-free tube attachment and threaded port engagement
• 1000 psi maximum working pressure for demanding fluid and gas service
• Operating temperature range of -65 degrees F to 250 degrees F
• Brass construction resists corrosion and supports reliable long-term sealing
• NPTF thread standard delivers a pressure-tight fit without relying solely on sealant

Compatibility

Designed as an OEM-style replacement or direct-use compression tube female elbow for systems requiring a 3/8-18 NPTF threaded port connection with a compression tube inlet.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or pipefitter familiar with compression and NPT fitting assembly. Shut off system pressure and isolate the line before disassembly or installation. Apply thread sealant or tape to the NPTF threads per the system manufacturer and applicable code requirements, such as the IPC or IFGC. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
