So when your customer's injection mold tool needs swapping out mid-shift, they're reaching for a quick-release coupling that won't leak under that high-pressrue line—we've seen shops lose half a day to a seized or poorly sealed coupler, and this KV series is built to avoid exactly that headache.
We're working with 304 stainless througout, so corrosion resisance is solid even with water-glycol fluids, and the vacuum plating on the surface actually helps maintain those tight tolerances over repeated cycles—most buyers go with the metric thread option, but we also stock BSPP if that's what your manifold uses.
The pressure rating hits 350 bar (roughly 5075 psi), which is better than some general-purpose couplings we've handled, and the flow rate comes in at 30 L/min for the standard size—though if you need higher flow our company can usually adjust the core design, just confirm lead time (usually 3-4 weeks for non-stock variants).
It's not suited for continuous high-temperature loops above 120°C because the nitrile seal starts to degrade; we've had a few buyers try pushing it to 140°C and the seal life drops by half or so, so if you're running hot oil, you'd want to ask about a Viton option instead.
One thing that's easy to overlook is the round head style—it actually makes a difference when you're working in tight mold base cavities, as the smooth profile doesn't snag on hoses or adjacent fittings, and quick-release mechanism itself is tool-free, which your floor guys will appreciate during those 50-unit changeovers or so.
ISO, DIN, and ANSI compliance means it'll mate with most standard couplers on the market, but we've noticed the thread tolerances are tighter than some imported alternatives, so you might need to check your female port's thread class if you're retrofitting old equipment.
Our standard MOQ for the KV Series is 100 pieces per size, but we can negotiate smaller batches for first-time orders or sample requests.
Yes, we supply ISO 9001 compliance certificates and test reports for pressure and leakage upon request. Just let us know what specific documents your QC needs.
The nitrile rubber seal is compatible with mineral oils and water-glycol fluids. For aggressive chemicals or high-temp applications, we'd recommend swapping to a Viton seal.
The vacuum plating gives good corrosion resistance, but it's not as tough as electroless nickel. For constant moisture or chemical exposure, we suggest upgrading to 316 stainless steel.
Stock items ship within 7–10 working days. For production runs of 500 units, expect 3–4 weeks, depending on thread configuration and surface finish.
