We've seen a lot of buyers struggle with threaded joints that seize or leak under moderate pressure, especially when the system undergoes thermal cycling.
For the DN15 up to DN100 range, these couplings handle a working pressure range of PN10 to PN16 (which translates to about 150 to 240 PSI depending on the size), and it's a full-flow design so you're not throttling anything—the PTFE seal matrial makes it pretty much acid and alkali resistant too.
Basically, if you're running at 60°C or below it's fine, but push beyond that and PVC-U gets soft, not a product suited for hot process lines. The 5L drum is easier to handle in my experience, plenty of buyers go with standard socket connections, but teh female/female option is there for existing thread installations.
Custom orders—like brand marking or different seal colors (check lead time)—are possible for larger volumes, usually 50 units or so for a trial run. Most buyers never think to ask about actuator mounting, but it follows ISO5211 standard, which makes automation retrofits straightforward.
Lead time is roughly 20 days for standdard sizes, give or take depending on the volume; we usually have stock on DN20 up to DN50, but confirm for the bigger ones. Production hits about 600,000 sets per year, so capacity isn't normally the bottleneck.
We can usually handle MOQs as low as 100 sets for standard sizes, but for DN80 and DN100 we might ask for 200 sets since production runs are a bit bigger. If you need less, just let us know and we'll see what we can do.
For stock sizes like DN15-DN50, lead time is typically 15-20 days after order confirmation. Larger sizes or custom orders might take 25-30 days, but we'll confirm when you place the order.
Yes, we include an ISO9001 certificate with each batch, and we can also provide a material test report for the PVC-U if you need it for your records. Just request it when you order.
We can swap the PTFE seal for something like EPDM or NBR if your application needs it, but that would be a custom order and might increase lead time a bit. We'd recommend sticking with PTFE for most standard uses.
Keep them in a dry area away from direct sunlight, ideally between 0°C and 40°C. Stack them neatly so the threads don't get damaged, and avoid contact with any harsh solvents.
