OEM/ODM Hex 10*16mm Flanged Pipe Fittings Manufacturer with 6 Months Warranty

So you’re building out a gas system or maybe a sewage treatment line, and you’ve got that one joint where a standard pipe just won’t seat right—too much vibration, or teh flange needs to hold under pressure—and you’re tired of fittings that loosen up after a few weeks. We see that a lot from buyers in public works projects, and what we do is machine these hex 10*16mm flanged fittings to lock in place without that creep. It’s basically a male connection, so you thread it straight into the female port and the flange gives you that extra bite.

Matrial-wise, you can pick brass, copper, or stainless steel depending on your enviroment—most buyers go with brass for cost and corrosion resistance, but if you’re dealing with aggressive chemicals in wastewater side, stainless is tighter. The specs run 1/4*1/2 or 1/2*3/4, and we hold those to within 0.1mm tolerance, which is better than a lot of standard fittings you’ll find. Purity on the brass is about 99.5% copper content, give or take, and the golden color comes from a passivation step that also helps with oxidation—handy if the fitting sits outdoors.

You’ll see these used in power stations where they need to handle steam cycling, and also in gas systems where a leak is just not an option—but here’s the thing, they’re not great for high-pressure hydraulic lines above 300 psi because the flange itself adds a stress point that can fatigue over time. Usually we ship in standard cartons stacked on a pallet, and the 6-month manufacturing defects, not wear from overtightening. One detail buyers often miss is the hex size: 10*16mm means the wrench flat is 10mm, so you’ll need a 10mm socket or open-end—don’t grab a 3/8-inch and round it off.

And if you need a sample, we’ll send one out—usually takes 2-4 weeks depending on your location. We also do custom lengths or thread pitches if your project calls for something off-spec, but the MOQ on those is about 500 units or so.
