Midland Industries 04056-1008 Brass Reducing Flare Union

Product Description

The MIDLAND INDUSTRIES 04056-1008 is a brass reducing union designed to connect two SAE 45-degree flared tube ends of different sizes. Connection 1 is 5/8 inch SAE 45-degree flare with a 7/8-14 thread; Connection 2 is 1/2 inch SAE 45-degree flare with a 3/4-16 thread. The fitting measures 1.87 inches in length with a 0.87-inch hex and weighs approximately 0.16 pounds. Rated to 650 psi and suitable for service between -65 and 250 degrees F, this union is installed by licensed plumbers and HVAC technicians working with refrigerant, fuel gas, or hydraulic line assemblies.

This reducing flare union is used in residential and light commercial applications wherever a SAE 45-degree flared line must transition from 5/8-inch to 1/2-inch tubing. Typical install scenarios include refrigerant line repairs, fuel supply connections, and hydraulic system assemblies. The fitting is compatible with aluminum, brass, copper, and steel hydraulic tubing with a minimum wall thickness of 0.035 inches. Its all-brass construction makes it appropriate for both indoor and outdoor installations where corrosion resistance is required.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with flare fitting assembly. Shut off and depressurize the line completely before disconnecting any fittings. Use two wrenches when tightening to prevent tube rotation and avoid overtightening, which can crack the flare seat. Verify flare geometry and tube wall thickness before assembly to ensure a leak-free connection.
