Cerrobrass 70A-4B Compression Female Elbow 1/4 in Brass

Product Description

The CERROBRASS 70A-4B is a brass compression tube female elbow designed to connect 1/4 inch OD tubing to a 1/4 NPT female threaded port at a 90-degree angle. It transitions from a compression-style tube connection to a female NPT (FNPT) pipe thread, making it a common choice when routing copper or other soft tubing into a threaded fitting body. The fitting is rated to 400 psi maximum working pressure and carries a temperature range of -65 degrees F to 212 degrees F, making it suitable for a broad range of fluid and gas service applications. The thread standard is SAE with a 7/16-24 thread size on the compression end. Plumbers and HVAC technicians install this fitting in both new construction and service work.

This female elbow sees use in residential and light commercial applications wherever a direction change is needed between a compression tube run and an NPT-threaded component. Typical installations include fuel gas lines, refrigeration, hydraulic, and pneumatic systems where 1/4 inch OD tubing meets a panel-mount or valve body with a 1/4 NPT female port. The all-brass construction suits potable water, fuel, and instrument-grade service lines. It conforms to SAE standards and meets Proposition 65 requirements.

Key Features

• Compression x FNPT end connections allow a direct tube-to-pipe-thread transition at 90 degrees
• Rated to 400 psi maximum working pressure for reliable performance in pressurized systems
• Brass construction provides corrosion resistance and durability across a wide range of media
• Accepts 1/4 inch OD tubing on the compression end with a 7/16-24 SAE thread interface
• 1/4 NPT female pipe thread on the outlet for compatibility with standard threaded components
• SAE-compliant and Proposition 65 listed

Compatibility

Designed as an OEM-style compression tube female elbow fitting for systems using 1/4 inch OD tubing and 1/4 NPT female-threaded ports in HVAC, plumbing, fuel, and pneumatic applications.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system completely before removing or installing any compression fitting. Do not overtighten the compression nut, as excessive force can deform the ferrule and cause leaks. Verify thread compatibility and confirm all connections are leak-free before returning the system to service.
