So when you're dealing with high-pressure hydraulic lines that see constant vibration and thermal cycling, the seal integrity here is what tends to fail first in a lot of standard fittings—we've seen it happen in mobile equipement applications mainly, and it's why our company offer multiple seal types like the O-ring or 60° cone options that handle the shift much better than a basic flat seal would.
Pricing depends partly on surface treatment, obviously, but actually most buyers go with the zinc-plated carbon steel as a workhorse for general industrial use and it holds up fine up to about 3500 PSI, though for anything pushing that 6000 PSI ceiling you'll want to step up to stainless with passivation, which is pricier but you don't want to guess on that one.
our company can run these in DIN, JIS, SAE, BSP, ISO, or Metric threads depending on what your system calls for, and the MOQ is typically 100 pieces but don't let that number scare you—we're pretty flexible on that (especially if you're testing a new assembly line) and the lead time is about 15-25 days give or take, though sometimes we have stock and can ship faster.
Customiaztion's avaliable too for OEM runs, but just a heads-up—these aren't suited for food-grade or sanitary lines because that zinc plating won't pass certain inspections, and if you're after a super smooth internal bore for minimal restriction, our 24° cone O-ring seal design actually gives you tighter tolerance than most standard multiseal options in the same size range.
Anyway, drop me the thread type and working pressrue range you're targeting and I can check what we've got in the 1/4" through 2" range within a day or so—there's a batch we just finished for another client that might line up well.
MOQ is 100 pieces normally, but for custom thread types like JIC, NPT, or SAE, we can negotiate lower quantities if you're testing or doing a small run. Just let us know what you need.
Yes, we include both ISO 9001 and RoHS compliance documentation with every order. Just request them when you place the order, and we'll attach the certs to your shipment.
Yes, carbon steel versions with zinc plating are rated up to 6000 PSI depending on the specific series and thread type. Just make sure to confirm the exact model with us if you need that high pressure consistently.
We use standard export packaging — usually sealed polybags inside sturdy cartons, with foam or cardboard dividers for thread protection. For stainless steel passivated fittings, we add extra rust-proofing layers.
Standard lead time is 15 to 25 days, even for mixed thread types like BSP and NPT. If you need it faster, we can sometimes expedite for an additional fee — just ask.
