You’ve got air tools locking up or leaking in a dusty, oily shop floor—standard couplers just don’t hold up. ball-locking mechanism on these is basically the same proven design, but the real difference shows when you’re swapping tools fast and the connection stays tight without that annoying hiss.
We’ve run these in environments where temps swing from -40°F to 225°F, and the seals—NBR or Viton depending on what you order—handle it without getting brittle or swelling. Max presure is 150 PSI, and at 100 PSI you’re moving 35 SCFM, which is enough for most impact wrenches and grinders. The hex head makes instalation straightforward with a standard wrench, and the barb connection (6.35mm, 8mm, or 10mm) is what you’d expect for push-on hose.
Material options are brass, steel, or stainless steel (usually 304 or 316), and surfce treatment can be chrome, nickel, or copper plated—though most buyers go with the nickel for general shop use. It’s ANSI standard, so it’ll mate with common plugs, but we’ve seen some guys try it with non-standard fittings and get a partial seal. Not suited for liquid lines or continuous high-pressure hydraulic use—the flow rating assumes compressed air only.
Compliance is ROHS, REACH, and CE, and we do a 1-year warranty on defects. Custom drawings or samples are accepted, but lead time can stretch to 20 days or so if you need a non-stock combination of materail and plating. We usually have the 8mm brass with NBR seals in stock, but confirm before ordering if you need Viton or stainlss—those are typically made to order.
We typically start at 500 pieces per size, but we can negotiate lower quantities for sample orders or first-time buyers.
Yes, custom plating such as copper on stainless steel is doable. Lead time is usually 15-20 working days after drawing approval.
Absolutely. We provide ROHS, REACH, and CE compliance docs with every order, so you can pass audits without hassle.
Yes, Viton seals are rated for up to 225°F continuous, and they hold up well in oily or chemical-heavy environments.
Sure. We pack in polybags then cardboard cartons, and for large orders we can use custom trays or foam inserts if you need extra protection.
