Midland Industries Copper Tubing & Fittings

Overview

The MIDLAND INDUSTRIES 38222 is a brass male adapter fitting designed to connect 3/8 inch tube OD copper tubing to a 3/8 inch male NPTF threaded port. Built for SAE Type A and B copper tubing systems, this adapter provides a reliable, leak-resistant transition between compression-style tube connections and standard tapered pipe thread fittings. Rated to 150 psi with a service temperature range of -40 to 200 degrees F, it is suited for plumbing, HVAC, and D.O.T. air brake copper tubing applications. The 17/32-24 thread specification and 0.69 inch hex flat allow for straightforward installation with standard hand tools. This adapter is commonly installed in residential and light commercial HVAC and plumbing systems wherever SAE copper tubing must terminate at an NPTF-threaded port or manifold. It is also listed for use in D.O.T. air brake copper tubing assemblies, making it a crossover fitting used by HVAC technicians, plumbers, and fleet maintenance professionals working with compressed-air or fluid-carrying copper tube lines. Key Features 3/8 inch tube OD compression end connects directly to SAE Type A and B copper tubing 3/8 inch male NPTF tapered thread provides a pressure-tight seal at the mating port 150 psi working pressure rating suitable for low-pressure fluid and air brake circuits Service temperature range of -40 to 200 degrees F covers most HVAC and plumbing environments Brass construction resists corrosion in water, refrigerant-adjacent, and compressed-air…
