48 pieces or so is where most buyers start, and you'll see sample pricing for a handful if you need to test fit something specific before committing. Mid-tier quantities, like a few hundred, drop the per-unit cost pretty dramatically, and bulk runs push it down further — that's where the real value snaps into focus for anyone doing regular builds or maintenance.
The bodies are nickel-plated brass, which basically resists corrosion better than plain brass in a shop enviroment, and push-to-connect mechanism works with PU or PA tubing from 4mm all the way up to 16mm. Thread options cover 1/8-inch to 1/2-inch, and even the BSW sizes are available (give or take a thread pitch), but who stocks everything anyway. Rough presure range is 0 to 0.8MPa working, with a max around 1.2MPa, which covers most air and vacuum lines. The temperture window is 0 to 60°C, so don't push them near hot machinery.
We always check the DIN tolerance on the collet ring with a digital caliper before packing — that seal has to be tight under pressure fluctuations or you'll get weepage. Also the nickel finish is pretty thin, so if you're handling caustic chemicals instead of air, these are not the fitting for that job, and there's no use pretending otherwise.
Each order comes with a batch-specific COA by default — HPLC verified, though we usually just run the low-end HPLC because it's fast and reliable enough for this grade. Packaging is by the box (usually quantity-matched to your order), and you get the TDS and SDS separate if needed, which is pretty standard.
Anyway, some buyers go straight for the 8mm size with 1/4-inch threads, because that's basically for pneumatic systems — the 5m-length tubing coil is easier to handle for routing. The difference between a 10-pack and a 500-piece bulk order is about, when I last checked, two-thirds off the piece price.
You'll get the fittings in their cases, a paper with torque specs (not that you need torque with push-to-connect), and we hand-count every hundred units because automated counters sometimes miss one in a pan batch — it's a small thing but it matters for consistent runs.
The max working pressure is 0.8MPa, and it can handle up to 1.2MPa as a peak. Stick to the 0.8MPa limit for regular use to keep things safe.
Yes, they're compatible with PU and PA tubes from 4mm up to 16mm — sizes like 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm are all supported.
They're CE, ROHS, and SGS certified, so they meet standard quality and safety requirements. We can provide the cert docs upon request.
MOQ is typically 100 pieces per size, but we can be flexible for trial orders. Lead time is usually 7-15 days depending on the quantity and model.
We can customize thread sizes based on your specs, and packaging options like bulk or individual bags are available. Just let us know what you need.
