Midland Industries 246X6X6 Brass Flare Adapter 3/8 in

Product Description

The MIDLAND INDUSTRIES 246X6X6 is a brass flare-to-female pipe adapter designed to connect SAE 45-degree male flared tubing to a female National Pipe Thread Fuel (FNPTF) port. The fitting accepts a 3/8-inch flared connection on one end and a 3/8-inch FNPTF threaded connection on the other, with a thread specification of 5/8-18 x 3/8-18. Overall length is 1.25 inches with a 0.81-inch hex for standard wrench engagement. Rated to 1000 psi and suitable for operating temperatures from -65 to 250 degrees F, this adapter is built for demanding hydraulic and fluid-line applications. Plumbers, HVAC technicians, and hydraulic system installers use this fitting where flared tubing must transition to a threaded female port.

This adapter is suited for residential and commercial hydraulic tubing systems where a reliable flare-to-pipe-thread transition is required. It is compatible with aluminum, brass, copper, and steel hydraulic tubing that can be flared. Typical installation scenarios include fuel lines, refrigeration piping, hydraulic circuits, and other pressurized fluid systems that use SAE 45-degree flare connections meeting the 0.032-inch minimum tube wall thickness requirement.

Key Features

• Brass construction for corrosion resistance in hydraulic and fluid-line service
• SAE 45-degree male flared inlet mates with standard flared tubing ends
• FNPTF outlet provides a fuel-rated female pipe thread connection
• Rated to 1000 psi for pressurized hydraulic and fluid applications
• Operating temperature range of -65 to 250 degrees F
• 0.81-inch hex allows standard open-end or adjustable wrench installation

Compatibility

Compatible with aluminum, brass, copper, and steel hydraulic tubing that can be flared, with a minimum tube wall thickness of 0.032 inches. Thread sizes are 5/8-18 (flare side) x 3/8-18 (pipe side).

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or hydraulic systems technician. Depressurize and isolate the fluid system completely before removing or installing any fittings. Use a backup wrench on the mating component to avoid twisting connected tubing when tightening. Ensure the flared tubing end is properly formed and free of cracks or distortion before assembly to maintain the rated pressure seal.
