Each union gets tested before it leaves the facility — we check for thread fit, presure tolerance, and material consistency using a random sampling protocol across every production lot and we'll send the COA with the shipment if you ask for it, though it's not automatically included in the standard order.
We have a retest policy if the first batch doesn't meet your QC standerds but you'll need to request it within 10 days of receipt and cover return shipping on any disputed units, and the samples we send are usually from the same production run so what you see is pretty much what you'll get.
For the barstock version, working pressure hits 1000 PSI which is better than casting's 125 PSI — most buyers running compressed air lines or high-flow water systems go with barstock, but for standerd residential or light commercail plumbing the casting units work fine and cost less (roughly 15-20% discount depending on volume).
The tempearture range from -40°F to 250°F covers most indoor and outdoor application, though if you're pushing past 200°F continuously you'll want to check thread sealant compatibility because some standard tapes degrade around that point.
We also do XRD testing on the brass for lead content verify it stays under the NSF/ANSI threshold, and the batch consistency from one 1000-piece order to the next is typically within 0.5% tolerance on thread dimensions (we keep the same die set for the full run).
Anyway, the OEM branding means you get your logo on the inner bag and outer carton — packing is polyethylene bags inside corrugated cartons, and we can split a 1000-piece MOQ across a few sizes (usually 1/4F and 1/2F mix) if you ask beforehand, but don't expect that on a first order without confirming lead time.
The barstock version is machined from solid brass and handles up to 1000 PSI, while the casting version is made from a mold and rated for 125 PSI. Both are lead-free, but choose barstock if your system needs higher pressure capacity.
Yes, samples are available. Just reach out with your address and we’ll send one out—usually takes a week or so. The sample cost is typically refunded once you place the bulk order.
We can provide material test reports and a lead-free compliance certificate per ANSI standards. Just let your account manager know which docs you need, and we’ll include them with the shipment.
Each union goes in an inner plastic bag, then packed into sturdy outer cartons. That’s our standard for bulk orders, and it’s held up fine for years of exports. No special crating needed unless you request it.
Absolutely—we offer OEM service, so we can put your brand on the unions or the packaging. For sizes outside the 1/4F to 3/4F range, just tell us what you need and we’ll see if we can adjust the tooling.
