Midland Industries 10237 Brass Flare Adapter 3/8 X 1/2

Product Description

The MIDLAND INDUSTRIES 10237 is a brass SAE 45-degree flare adapter designed to transition between a 3/8-inch male flared connection and a 1/2-inch female NPT (FNPTF) threaded port. The fitting handles working pressures up to 1000 psi and operates across a temperature range of -65 to 250 degrees F. Thread dimensions are 5/8-18 on the flare end and 1/2-14 NPT on the female side, with a 1-inch hex for wrench engagement. Overall length is 1.6 inches. Licensed plumbing and HVAC technicians use this adapter when connecting copper, brass, aluminum, or steel hydraulic tubing to NPT-ported equipment or manifolds.

This adapter is suited for hydraulic and fluid-transfer systems that require a leak-free transition from a 45-degree flare fitting to a standard female pipe thread port. Typical installations include hydraulic lines, refrigeration piping, fuel systems, and other closed-loop fluid circuits where both pressure integrity and vibration resistance are required. The brass construction resists corrosion in a wide range of media and makes the fitting appropriate for both residential and light commercial service work.

Key Features

• SAE 45-degree male flare x 1/2-inch FNPTF configuration for common transition applications
• Rated to 1000 psi working pressure for hydraulic and high-pressure fluid service
• Temperature range of -65 to 250 degrees F suits refrigeration and heating system use
• Brass construction compatible with copper, brass, aluminum, and steel hydraulic tubing
• 1-inch hex flats allow standard wrench installation without slipping
• Minimum tube wall thickness of 0.032 inches specified for flare-end compatibility

Compatibility

Designed for use with copper, brass, aluminum, and steel hydraulic tubing in SAE 45-degree flare systems. Compatible tubing requires a minimum wall thickness of 0.032 inches at the flare end.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or hydraulic systems technician familiar with SAE 45-degree flare connections. Shut off all system pressure and depressurize the line before removing or installing any fittings. Use a backup wrench on the mating fitting to avoid twisting or stressing connected tubing. Do not over-torque brass fittings, as this can distort the flare seat and cause leaks.
