Midland Industries 00066-0806 Light Pattern Adapter 1/2 Inches Compression X 3/8 Inches Fnpt Brass

Product Description

The Midland Industries 00066-0806 is a light pattern brass adapter designed to connect a 1/2 inches compression fitting to a 3/8 inches female NPT threaded port. This fitting is a practical solution for plumbers, HVAC technicians, and pipefitters who need to transition between compression-style tubing connections and standard female NPT threaded fittings in a single compact component. The adapter is machined from solid brass, which provides reliable corrosion resistance and long service life in both residential and light commercial applications. Brass fittings like this one are a trusted choice in the trade for water supply lines, refrigeration lines, and gas service connections where durability and leak-free performance are required. The compression end accepts copper, aluminum, and thermoplastic tubing, giving installers flexibility across a wide range of job types. The 1/2 inches compression side uses a standard ferrule and nut to grip and seal the tubing without soldering or special tools, making installation fast and straightforward. The 3/8 inches FNPT end threads onto male-threaded valves, fixtures, or equipment ports with ease. With a pressure rating of 200 psi and a temperature range of -65 to 250 degrees F, this adapter performs reliably in demanding conditions including chilled water systems, potable water distribution, and compressed air lines. The hex size of 0.81 inches allows for easy wrench tightening without over-stressing the fitting body. The center-to-end dimension of 0.94 inches keeps the overall assembly compact, which is especially useful in tight spaces behind walls or inside equipment cabinets. This adapter is a dependable, code-acceptable component for a wide variety of plumbing and mechanical installations.
