Midland Industries 248X8X12 Half Union Adapter Brass

Product Description

The MIDLAND INDUSTRIES 248X8X12 is a brass half union adapter designed to connect SAE 45-degree male flared tubing to a male pipe thread (MPT) port. It transitions a 1/2-inch flare connection to a 3/4-inch MPT thread, making it a practical fitting for hydraulic and fluid-transfer lines where a rigid tube meets a threaded port. Rated to 750 psi and suitable for operating temperatures from -65 to 250 degrees F, this adapter is built for demanding service environments. The 1.06-inch hex provides clean wrench engagement, and the all-brass construction resists corrosion across a wide range of compatible media.

This adapter is used in hydraulic plumbing applications involving aluminum, brass, copper, or steel tubing that can be flared to the SAE 45-degree standard. It is a common component in mobile hydraulic systems, refrigeration lines, and industrial fluid circuits where a flare-to-pipe-thread transition is required. Plumbers, pipefitters, and hydraulic technicians typically install this fitting during system assembly or repair. It is appropriate for both light commercial and industrial installations where SAE flare fittings are specified.

Key Features

• SAE 45-degree male flare on side one transitions to 3/4-inch MPT on side two
• Rated to 750 psi for use in pressurized hydraulic and fluid-transfer lines
• Operating temperature range of -65 to 250 degrees F
• All-brass construction for corrosion resistance and durability
• 3/4-16 x 3/4-14 thread specification with 1.06-inch hex for standard wrench access
• Compatible with aluminum, brass, copper, and steel hydraulic tubing rated for flaring, with a minimum 0.032-inch tube wall thickness

Compatibility

Designed for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared to the SAE 45-degree standard, with a minimum tube wall thickness of 0.032 inches.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified hydraulic technician. Depressurize and drain the system fully before removing or installing any fittings. Apply thread sealant to the MPT threads in accordance with the applicable installation standard, and ensure the flare seat and tubing flare are free of debris or damage before assembly. Do not overtighten the flare nut, as this can distort the seating surface and cause leaks.
