Teh sealed casting process is what sets these apart — it’s not just a suface treatment, but a full-density pour that eliminates internal voids, so you don’t get weak points under torque or repeated sterilization cycles, and we’ve seen these hold up better than standerd brass fittings in oral surgery setups where moisture and chemical exposure are constant.
Each batch runs through a three-stage check: first a visual polish inspection for the smooth yellow finish, then a dimensional gauge test against the thickened wall spec, and finally a salt-spray rust-proofing trial that runs 48 hours, typically hitting zero corrosion, though we’d recommend you run your own COA verification on arrival given the MOQ of 100 pieces.
You’ll get an ISO and CE marking with every shipment, but what that actually means is alloy composition is held to a tighter tolerance than most generic brass castings — about 0.5% variance in copper content across runs — and we retain a sealed sample form each lot for 90 days in case there’s a retest dispute, which happens maybe once every 200 orders or so.
The wall thickness is roughly 2.8mm on the main body, which is thicker than the for dental accessories, and that matters when you’re clamping or adjusting these under repetitive load — they don’t deform or crack like the thinner ones do, and we’ve had buyers use them for 18 months straight without a replacement.
Also, if you need OEM work, our company can adjust the bore diameter or thread pitch, but the minimum for custom tooling is 500 pieces (usually a 6-week lead time), and we don’t offer small-batch color changes — it’s always yellow brass unless you’re ordering a full container lot.
That MOQ is set at 100 pieces per order, so if you're a smaller lab, you'd need to commit to that quantity upfront. We can't split it into smaller batches for the initial run.
Yes, we can supply a material certificate with the shipment confirming the brass (all-copper) composition. Just request it when you place the order.
Lead time is typically 15-20 working days after order confirmation, depending on current production load. We'll give you a precise date once we check our schedule.
We can discuss custom finishes as part of our OEM service, but the standard for this model is polished smooth. For a different finish, there may be additional tooling costs and a slightly longer lead time.
The brass material is inherently rust-proof, and we test the surface for corrosion resistance during QC. We don't have a separate sterilization certification, but it's suitable for standard dental autoclave environments.
