Midland Industries 00068-0806 Compression Adapter Brass

Product Description

The MIDLAND INDUSTRIES 00068-0806 is a light pattern compression adapter designed to transition between a 1/2-inch compression connection and a 3/8-inch male NPTF threaded connection. Machined from brass, this adapter is rated for up to 200 psi and handles temperatures ranging from -65 degrees F to 250 degrees F. The hex measures 0.68 inches, and the center-to-end dimension is 1.16 inches. Plumbers and HVAC technicians install this fitting where copper, aluminum, or thermoplastic tubing must connect to a male NPTF port on valves, meters, or supply lines.

This adapter is suited for residential and light commercial plumbing and HVAC applications. It is commonly installed on gas meter sets, water supply lines, and refrigeration or fuel lines where a compression-to-NPTF transition is required. The fitting accommodates copper, aluminum, and thermoplastic tubing on the compression side, making it a flexible choice across multiple piping systems. Its compact, light-pattern profile is appropriate for tight spaces and standard service conditions within its rated pressure and temperature range.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IFGC requirements. Shut off the supply line and relieve all pressure before disassembly or installation. Do not overtighten the compression nut, as brass fittings can crack under excessive torque. Inspect the compression sleeve and tubing end for burrs or damage before making the final connection.
