High-Purity & UHP Fittings for Semiconductor

Superlok® USA · Semiconductor & UHP In a Fab, a Wafer Is Only as Clean as the Gas Line Feeding It The U.S. is pouring hundreds of billions into new fabs. Every one of them runs on ultra-high-purity gas, and a single particle in the line can scrap a wafer worth more than the fitting a thousand times over. $100BMicron’s new megafab in Clay, New York, one of many now breaking ground ~20%the jump in global semiconductor capex expected in 2026 (SEMI) Electropolishedthe interior surface finish ultra-high-purity gas lines demand The chip build-out in America is not a forecast anymore, it is a construction site. Between 2023 and 2025 the industry launched 97 new high-volume fabs, TSMC has guided its Arizona investment toward $165 billion, Micron just broke ground on a $100 billion megafab in New York, and 2026 capex is set to climb about 20 percent. Every one of those fabs comes down to the same quiet dependency: ultra-high-purity gas, delivered to the wafer without a particle, a molecule of moisture, or a trace of oxygen out of place. That is what a high-purity fitting is really for, and it is exactly where Superlok® lives: UHP instrumentation fittings and

High-Pressure Hydrogen Fittings

Superlok® USA · Hydrogen Systems High-Pressure Hydrogen Is Only as Safe as the Fitting Holding It Hydrogen dispenses at 700 bar into a molecule small enough to find any weak joint. At that pressure, the fitting and its alloy are the safety case, not an afterthought. 700 barthe pressure a modern hydrogen dispenser delivers, roughly 10,000 psi 316/316Laustenitic stainless that resists hydrogen embrittlement when the nickel is right Same daymost in-stock Superlok® orders ship when placed during business hours Hydrogen is one of those build-outs that looks quiet until you stand next to it. Federal hub funding wobbled in 2025, but the physical infrastructure kept going in: retail stations dispensing at 700 bar, heavy-duty truck corridors, electrolyzer and industrial gas projects. California alone has more than fifty retail stations running, and a single heavy-duty site can dispense up to 18,000 kilograms of hydrogen a day. Every one of those systems comes down to a lot of small connections that have to hold a very small molecule at very high pressure. That is what a high-pressure hydrogen fitting is really for, and it is exactly where Superlok® lives: 316/316L instrumentation fittings and valves, specified right, from stock. 700 barDispensing pressure −40°CFast-fill pre-cool ≥12%

The U.S. Energy Boom Is Back, and It Runs on Parts That Have to Hold

Superlok® USA · 2026 Energy Outlook The U.S. Energy Boom Is Back, and It Runs on Parts That Have to Hold Record crude output and the biggest pipeline build-out since 2008 mean more instrumentation, more pressure systems, and a lot less patience for a back-ordered fitting. 13.6Mbarrels a day, the 2025 U.S. crude record the EIA expects to hold in 2026 44.9 Bcf/dnew gas pipeline capacity planned for 2026–27, the most since 2008 (EIA) Same daymost in-stock Superlok® orders ship when placed during business hours American energy is running wide open again, and the numbers are hard to argue with. The U.S. hit an annual crude record of 13.6 million barrels a day in 2025, and the EIA expects output to stay right near that mark through 2026. The Permian alone is pumping about 6.0 million barrels a day, roughly 44 percent of everything the country produces, plus 22 Bcf/d of natural gas. Downstream, operators have lined up 44.9 Bcf/d of new pipeline capacity for 2026 and 2027, the largest build-out since 2008, and more than two-thirds of it starts in Texas. From the wellhead in West Texas to the LNG trains on the Gulf Coast, crews are building. And building means

I can’t say enough good things about Superlok! Their service is top-notch, their turnaround time is lightning fast, and their support is absolutely next level. I came in unsure of exactly what fittings I needed, and Karren went above and beyond to help me sort it out. She was incredibly knowledgeable, patient, and made sure I left with exactly what I needed. If you’re looking for a place that knows their stuff and genuinely cares about getting you the right solution the first time—this is it. Huge thanks to Karren and the whole team!

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.

Excellent customer service! Immediately reached a person and they went out of their way to solve my problem. In the end I didn’t even make a direct purchase from them this time because they were able to troubleshoot my issue and come up with a solution over the phone. Thank you Wren!!

While installing some import German equipment we needed to adapt from Metric to standard. 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. Customer service is not dead.... Rodney Lacy
