Midland Industries 10331U 90 Deg Elbow 3/4 Male Flare X 3/4 Fnptf

Product Description

The MIDLAND INDUSTRIES 10331U is a forged brass 90-degree elbow fitting designed to connect a 3/4-inch male SAE 45-degree flare end to a 3/4-inch female NPT (FNPTF) pipe thread. Built from forged brass for strength and corrosion resistance, this fitting handles pressures up to 550 psi and operates across a temperature range of -65 to 250 degrees F. The thread specifications are 1-1/16-14 on the flare end and 3/4-14 on the pipe end. It is installed by licensed plumbers, HVAC technicians, and hydraulic system technicians working on fluid and gas line assemblies that require a direction change from tubing to pipe thread connections.

This elbow is suited for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared to the SAE 45-degree specification. Typical applications include hydraulic lines, refrigeration-adjacent fluid systems, and gas distribution piping where a 90-degree directional change from a flared tube to a threaded pipe port is required. The fitting is rated for both high-pressure and wide-temperature-range service, making it appropriate for demanding industrial and mechanical installations. Minimum order quantity is 1.

Key Features

• Forged brass construction for strength and corrosion resistance
• 90-degree elbow configuration for compact directional changes in line routing
• SAE 45-degree flare connection on the male end at 1-1/16-14 thread
• Female NPT pipe thread (FNPTF) on the second end at 3/4-14 thread
• Rated to 550 psi working pressure
• Wide service temperature range: -65 to 250 degrees F

Compatibility

Compatible with aluminum, brass, copper, and steel hydraulic tubing that can be flared to SAE 45-degree specification. Requires a minimum tube wall thickness of 0.035 inches for proper flare formation and seal.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or hydraulic systems technician familiar with flare fitting assembly. Always depressurize and drain the line before disassembly or new installation. Use a calibrated flaring tool to achieve a clean, consistent 45-degree flare before seating the fitting. Apply thread sealant to the NPT side only - do not apply sealant to the flare seating surfaces, as flare connections rely on metal-to-metal contact for sealing.
