Midland Industries 10237L Light Pattern Adapter Brass

Product Description

The MIDLAND INDUSTRIES 10237L is a light pattern brass adapter fitting designed to connect 3/8-inch male flared tubing to a 1/2-inch female NPT tapered (FNPTF) port. Built to SAE 45-degree flare standards, it features a 5/8-18 male flare thread on one end and a 1/2-14 NPT thread on the other. The hex body measures 0.94 inches across flats, and overall length is 1.31 inches. Rated to 1000 psi working pressure with an operating temperature range of -65 to 250 degrees F, this adapter is suited for use in hydraulic and refrigerant line assemblies where a flare-to-pipe-thread transition is required.

This fitting is designed for use with copper, brass, aluminum, and steel hydraulic tubing with a minimum tube wall thickness of 0.032 inches. Typical applications include hydraulic system plumbing, HVAC refrigerant piping transitions, fuel line connections, and light industrial fluid systems where a reliable flare-to-NPT adapter is needed. The compact light pattern design reduces weight and bulk while maintaining rated pressure performance. Licensed plumbers, pipefitters, and HVAC technicians commonly install this fitting in both residential and light commercial service work.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing or installing any fittings. Apply thread sealant appropriate for the fluid type on the NPT side only - do not apply sealant to the flare seat. Torque the flare nut against the seat using two wrenches to prevent body rotation and avoid overtightening, which can crack the flare.
