Swagelok® quick connect fittings are common in systems that demand fast access and clean sealing but when you need an alternative that performs just as well, integrates cleanly, and gives you more control over sourcing, Superlok is the move.
SuperlokUSA® quick connect fittings offer the same push-to-connect convenience as Swagelok® QTM and QC series with options for valved and unvalved connections, panel-mount bodies, and NPT or compression tube ends. These fittings are engineered for reliable shutoff, leak-free sealing, and fast disconnection, making them ideal for use in pressure systems, sampling setups, and mobile test equipment.
Made from 316 stainless steel and other corrosion-resistant alloys, Superlok quick connects are compatible with sanitary stainless steel fittings and designed to handle frequent cycling, exposure to aggressive media, and tight spatial installs. Their robust sealing system supports high-integrity applications in hygienic fluid processors, clean in place instrumentation, and light industrial gas or liquid transfer.
Whether you’re maintaining precise fluid control in a panel build or routing process gases through quick-change analyzer loops, Superlok delivers the same form, fit, and function with cleaner availability and no compromise in spec. Every fitting is leak-tested, dimensionally matched, and supported by technical documentation giving you confidence whether you’re building new or swapping out legacy parts.

SuperlokUSA quick connect fittings are fully interchangeable with Swagelok and Parker equivalents. Designed to match form, fit, and function, Superlok’s quick connect couplings use the same push-to-connect body dimensions and thread specs, allowing seamless integration into existing fluid and gas systems without modification.
Thread tolerances are held to ASME B1.1 standards, with nut and body threads machined to the same strict dimensional controls used by legacy Swagelok fittings. Every unit is tested for leak integrity and sealing performance to ensure a consistent make-up each time.
A certified SGS intermix-ability and interchangeability burst-test report is available on request, verifying cross-compatibility in pressure systems, pneumatic networks, clean in place instrumentation, and precise fluid control setups.

Zachary AdlerOctober 18, 2024Trustindex verifies that the original source of the review is Google. I work in an academic lab, and we have been buying Superlok products for our gas lines. 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.
