Midland Brass Compression Plug for Tube Fittings
The Midland brass compression plug seals off the end of a tube or closes an unused port in a compression fitting, giving you a clean, leak-tight cap without soldering or adhesives. Machined from solid brass, it installs like any compression component — slide it into the nut and ferrule and tighten for a reliable, reusable seal on copper, aluminum, or thermoplastic tubing.
