Precision Parts. Purpose-Built. Ship-Ready.
Our lineup of tube fittings, hygienic valves, and instrumentation components is trusted in industries that run 24/7, tolerate zero failure, and require full compatibility with legacy Swagelok® and Parker systems. We support OEM (Original Equipment Manufacturer) builds, maintenance cycles, and critical infrastructure with parts that check every box cleanliness, compatibility, cost-efficiency, and control.
Need a quote on 1,000 units? Or just one critical part by tomorrow morning? We do both without drama.
No Weak Links. Just Strong, Corrosion-Resistant Connections.
In chemical manufacturing, every seal, weld, and valve is exposed to corrosive, volatile media. That’s why plant operators rely on SuperlokUSA for corrosion-resistant alloys, sanitary stainless steel fittings, and instrumentation-grade connections that hold up under brutal conditions. Our hygienic valves are ideal for applications requiring rapid flushing and zero contamination. Whether you're handling caustics, solvents, or acids, our parts maintain leak-tight integrity and full compliance without slowing your operations down.
We also support clean-in-place instrumentation systems designed for full system sterilization, reducing manual maintenance while keeping throughput high.

Previously, we used cheap connections that always came loose and leaked gases. Since we have switched to Superlok, we have had no issues of gas leaks. Their products are high quality with good prices. Wren has been very helpful with our orders, always sending updates on the status of our orders. I would definitely recommend Superlok.

We called Swedglok; the manufacture of the German end of the problem. It took 30 minutes to figure out what I was needing and to find that it will take a week to get it. I called Superlok. Wren knew right away what I was talking about. She had the solution in stock. During the exchange I needed to call her a number of times to up the quantity or change freight to early AM delivery. Wren was easy to reach and I felt her smile from my end of the phone. Good companies are made Great by the staff they employee. If this was an interview, I would hire Wren.
