This MSA stainless steel male union adapter gives you a rock-solid connection from 1/4" NPT to 3/4", with threads that don’t strip and a seal that doesn’t quit. Made from stainless steel, it’s built for jobs where brass won’t cut it — high pressure, corrosive environments, or sensitive gas work. The fit is clean, the install is simple, and once it's on, it stays put. If you’re working with air lines, monitors, or high-spec gas detection systems, this is the kind of fitting you can trust not to leak.
In Stock and Ready to Thread
No waiting around for backordered fittings — we’ve got these MSA union adapters in stock and ready to ship today. Whether you’re replacing a worn-out connection or building out a full system, we pack it, track it, and get it to your site fast. You need it tight and on time — we get that.
