When you're swapping out hydraulic lines in a tight, grimy spot and every second of downtime costs you, the last thing you need is a coupling that fights back or leaks under pressure. That's where this KV series quick coupling comes in—it's stainless steel, rated up to 350 bar, and handles temperatures from -20°C to +120°C without complaining. The thread lock is a real time-saver, basically keeping the connection secure even when things get bumpy.
Most buyers we deal with are running hydraulic systems on mobile equipment or in industrial plants where water, oil, or compressed air is the medium. The quick-release mechanism is what it is—you push, twist, and it's done, no tools needed. It's not suited for high-vibration environments where a standard coupling might back off, but the thread lock here helps a lot.
We've seen these couplings used in everything from agricultural machinery to construction gear, and the vacuum surface treatment makes a noticeable difference in corrosion resistnce compared to untreated stainless. The round head design is easier to grip with greasy gloves, and you've got both metric and imperial thread options depending on your setup. It meets both DIN and ANSI standard, so compatibility across systems is usually fine.
The K2 specifcation is the most common we ship, and it's typically in stock for around 50 units or so. Lead time is roughly 20 days from Foshan, Guangdong, but we recommend checking availability first. Packaging is standard carton, nothing fancy, but it gets the job done for safe dilevery.
Our standard MOQ for the KV Series stainless steel couplings is 50 pieces, but we can negotiate for smaller trial orders if you're just getting started.
Typical lead time is 15-20 working days for standard orders. If you need rush delivery, let us know and we'll see what we can do.
Yes, we can provide a material test certificate for the stainless steel and a pressure test report upon request. Just mention it when you place your order.
Sure, the K2 size comes in both metric and imperial threads—just specify which you need when ordering. Common choices are G1/4 or 1/4 NPT.
They come in standard cartons, individually wrapped to prevent scratches during transit. For bulk orders, we can also pack them in wooden crates if needed.
