Cerrobrass 70A-6B Compression Female Elbow 1/4 Npt

Product Description

The CERROBRASS 70A-6B is a brass compression tube female elbow fitting designed to connect tubing to a female NPT threaded port at a 90-degree angle. It uses a compression-style tube connection on one end and a female NPT thread on the other, providing a secure, leak-resistant joint without soldering or brazing. The fitting accepts 3/8-inch outside diameter tubing and connects to a 1/4-inch NPT pipe thread. Built to SAE standards, this fitting is commonly installed by licensed plumbers, HVAC technicians, and refrigeration mechanics working on fluid or gas distribution lines.

This elbow fitting is suited for residential and light commercial applications where a direction change is needed between a compression tube run and a threaded female port. Typical uses include fuel gas, refrigerant-adjacent tubing, hydraulic lines, and water supply connections where a 90-degree transition from compression tubing to a female NPT fitting is required. The all-brass construction handles the pressures and temperatures common to these service environments.

Key Features

• Compression x FNPT end connections allow tool-free tube insertion with wrench tightening on the NPT side
• 3/8-inch tube outside diameter compression end for secure, no-solder tube retention
• 1/4-inch NPT female thread conforms to standard pipe sizing
• 9/16-24 thread size on compression nut
• All-brass construction for corrosion resistance and durability
• Meets SAE standards for dimensional and performance compliance

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 3/8-inch OD compression tubing terminated at a 1/4-inch NPT female port, conforming to SAE fitting standards.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with compression fittings and NPT thread sealing. Shut off the fluid or gas supply and depressurize the line before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to the male NPT threads mating into this fitting; do not apply sealant to compression ferrule surfaces. Compression connections require proper ferrule seating and wrench tightening to achieve a leak-free joint - verify with a pressure test or leak detection solution after service.
