We've structured the WU Series pricing so you're not locked into a premium just for a single piece—sample orders start at a reasonable rate, mid-volume runs drop significantly, and bulk pricing is where the real savings kick in, usually around 30-40% below the single-unit cost depending on quantity.
What it does in practice is provide reliable metal-to-metal seal that holds up from deep vacuum all the way to high pressure, and we've seen these fittings perform consistently across that entire range without needing gasket swaps or retorquing.
The key numbers you'll care about are the surfce finish at 10μin. Ra on both glands and bodies, which is better than most standard fittings for this class, and the temperture range from -425°F to 1000°F—so it handles cryogenic and steam service without a hiccup.
It's actually built to ANSI/ASME B31.3 and B31.1 standard, which means it fits right into most industrial piping codes without extra paperwork, and our company offer it in 316, 316L, or 316L VAR stainless depending on your corrosion or purity needs.
One thing that's not obvious from the spec sheet is silver-plated threads—they prevent galling during instalation, which is a real headache with stainless-on-stainless connections, and the two test ports let you leak-check without breaking the seal.
Size range runs from 1/16" to 1", and the minimum order is just one piece, so you can try a sample before committing to a larger batch—OEM customiaztion is available too if you need different gasket materials like copper or nickel (usually 2-4 weeks lead time for that).
It means the fittings meet strict design and pressure standards for process piping, so they’re safe for high-pressure and high-temperature systems. You can use them confidently in vacuum or pressure applications up to 1000°F.
Minimum order is 1 piece, so you can grab a single fitting for testing or prototyping without any hassle. No need to buy in bulk upfront.
We offer a 10μin. (0.25μm) Ra surface finish, which is super smooth and ideal for ultrahigh purity or clean room uses. It reduces particle trapping and makes cleaning easier.
Yes, we offer OEM customization services, so we can adjust gasket materials (316L SS, copper, nickel) or other specs to fit your needs. Just contact us with your requirements, and we’ll work it out.
They’re manufactured in a clean room and double-bagged to maintain cleanliness. For sensitive uses, we can also do vacuum-sealed packaging on request.
