Basically if you're running potable water lines and dealing with dezincification issues—that's where these really come into their own, the CW602N and DZR brass grades our company offer are specifically designed to prevent that common corrosion problem, and with the +/-0.05mm tolerance on CNC-machined threads you get a seal that doesn't leak on the first pressure test.
Most buyers in HVAC and refrigeration go with the female connection option since it simplifies installation on existing copper or steel lines, but we've also done custom runs for furniture and toy manufacturers where they needed a specific head shape—round is standard but we can literally machine whatever profile you want form your CAD file.
20 days or so is the usual lead time after you confirm the order, but if you're running tight on schedule we can sometimes push it to 15 days for standard brass grades like HPb57-3 or 59-1, just confirm stock availability when you send the PO.
The plated copper suface treatment is pretty popular for exposed fittings in air conditioning systems because it matches the rest of the line visually, but we also do raw brass or any finish you specify—just keep in mind that custom surface treatments add about a week to delivery.
We test every batch with a projector for thread profile, hardness tester for materail consistency, and salt spray for corrosion resisance, but if you need specific certifications for potable water compliance (NSF or WRAS), let us know upfront so we can adjust the alloy selection and testing protocol.
Honestly these aren't great for high-pressure hydraulic systems above 3000 psi since brass has lower tensile strength than steel, but for water, refrigeration, and general machinery connections with pressures under 1500 psi they hold up better than most standard brass fittings you'll find off the shelf.
We don't have a strict MOQ — it really depends on the complexity and size of the fitting. For standard brass parts, we can start with as few as 100 pieces, but for highly customized runs, we'll discuss based on your volume.
Yes, we can supply mill test reports and material certificates for grades like HPb57-3, CW602N, or DZR brass. Just let us know which standard you need, and we'll include it with your shipment.
Our standard lead time is 20-30 days after order confirmation. If you need DZR brass with a custom surface finish like plated copper, it usually stays within that window, though complex treatments might add a few days.
We use CNC machining and check every batch with our projector, hardness tester, and roughness tester. For tight tolerances, we also do in-process inspections with height gauges to keep everything within spec.
Absolutely, we can customize the female connection to your specs. Just send over your drawing or requirements, and we'll adjust the thread type, depth, or angle to fit your refrigeration system needs.
