Midland Industries 248X10X12 Half Union Adapter Brass

Product Description

The MIDLAND INDUSTRIES 248X10X12 is a brass half union adapter designed to connect SAE 45-degree male flared tubing to a male pipe thread (MPT) port. It bridges a 5/8-inch flare connection to a 3/4-inch MPT fitting, making it a practical transition piece in hydraulic and fluid-transfer lines. The fitting is machined from brass and rated to 650 psi, with a temperature range of -65 to 250 degrees F. The 1.06-inch hex allows for standard wrench installation. This adapter is installed by licensed plumbers, hydraulic technicians, and mechanical contractors working on tubing assemblies that require a flare-to-pipe transition.

This half union adapter is suited for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared. It is commonly installed in hydraulic systems, refrigeration lines, fuel systems, and fluid-handling assemblies where a SAE 45-degree flare on the tubing side must connect to a threaded port or component. The 7/8-14 male flare thread and 3/4-14 male pipe thread sizing make it a standard choice for medium-pressure tubing runs in both commercial and industrial applications.

Key Features

• SAE 45-degree male flare x 3/4-inch MPT configuration for reliable flare-to-pipe transitions
• Brass construction resists corrosion and provides compatibility with a wide range of fluids
• Rated to 650 psi for medium-pressure hydraulic and fluid-transfer service
• Operating temperature range of -65 to 250 degrees F suits both low-temperature and elevated-heat environments
• 1.06-inch hex enables installation with a standard open-end or combination wrench
• Compatible with tubing having a minimum wall thickness of 0.035 inches

Compatibility

Designed for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared to SAE 45-degree specifications. Suitable for any system accepting a 7/8-14 male flare and a 3/4-14 male pipe thread connection.

Installation Notes

Installation should be performed by a qualified plumber, hydraulic technician, or mechanical contractor. De-pressurize and drain the system fully before removing or installing any fitting. Apply thread sealant appropriate for the fluid type to the MPT threads; do not apply sealant to the flare seating surfaces. Tighten to snug engagement with a wrench on the hex flat - do not over-torque brass fittings, as this can crack the fitting body or distort the flare seat.
