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

Product Description

The PARKER 170CA-8-6 is a brass compression tube female elbow fitting designed to connect compression tubing to a female NPT port at a 90-degree angle. It features a 3/8-18 NPTF thread and an end connection configuration of compression by FNPT. Rated for a maximum working pressure of 750 psi and a temperature range of -65 degrees F to 250 degrees F, this fitting is built for reliable performance in demanding fluid and pneumatic line applications. It is installed by licensed plumbers, HVAC technicians, and pipefitters working on instrumentation, refrigeration, or general fluid transfer systems.

This fitting is suited for residential and commercial applications where a direction change is needed between a compression tube line and a female NPT port. Common install scenarios include instrumentation tubing runs, HVAC refrigerant or oil line connections, and general-purpose pneumatic or hydraulic plumbing where a compact elbow transition is required. The brass construction offers good corrosion resistance across a broad range of compatible fluids and gases.

Key Features

• 90-degree female elbow configuration for direction changes in tubing runs
• Compression by FNPT end connections for tool-free tube insertion on the compression side
• 3/8-18 NPTF thread standard for a pressure-tight mechanical seal
• 750 psi maximum working pressure for demanding service conditions
• Wide temperature range: -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance and durability

Compatibility

Designed as an OEM-style replacement or direct-install compression tube female elbow fitting for systems requiring a 3/8-18 NPTF compression-to-FNPT transition in brass.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician. Depressurize and drain the system completely before removing or installing any compression fittings. Hand-tighten the NPTF threaded connection first, then apply thread sealant appropriate for the service fluid before final tightening. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
