Midland Industries 18162L Light Pattern Adapter Brass

Product Description

The MIDLAND INDUSTRIES 18162L is a light pattern brass compression-to-female adapter designed to connect 5/8-inch compression tubing to a 1/2-inch female NPT fitting (FNPTF). It serves as a transition fitting in plumbing, refrigeration, and mechanical systems where a compression tube connection must terminate at a threaded female port. The body is machined from brass, rated for 150 psi working pressure across a wide temperature range of -65 to 250 degrees F. The 0.94-inch hex flat makes it wrenchable for field installation. Plumbers, HVAC technicians, and mechanical contractors use this fitting where tubing transitions to a threaded pipe connection.

This adapter is suited for residential and light commercial plumbing and HVAC applications where copper, aluminum, or thermoplastic tubing must interface with a 1/2-inch female NPT port. Typical install scenarios include refrigeration service lines, water supply tubing connections, and low-pressure pneumatic or fluid-handling systems. The light pattern designation indicates a compact form factor appropriate for space-constrained installations.

Key Features

• 5/8-inch compression inlet to 1/2-inch FNPTF outlet transition
• Brass construction for corrosion resistance in plumbing and HVAC environments
• Rated to 150 psi working pressure
• Temperature range of -65 to 250 degrees F
• 0.94-inch hex flat for standard wrench engagement
• Compatible with copper, aluminum, and thermoplastic tubing

Compatibility

Designed for use with copper, aluminum, and thermoplastic tubing in compression-to-female NPT fitting applications. Thread sizing is 13/16-18 on the compression side and 1/2-14 NPT on the female threaded side.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Shut off the water or fluid supply and depressurize the line before removing or installing any fitting. Do not overtighten the compression nut, as this can deform the ferrule and cause leaks. Verify thread compatibility and tubing OD before assembly; use thread sealant on NPT threads as required by local plumbing code.
