You've likely dealt with enough cheap couplings to know exactly why you're looking at the K2 now—our company supply these to folks running hydraulic lines and pneumatic tooling setups where a blown connection isn't just an inconvenience, it's a shift-stopper.
It's built form 304 stainles with vacuum treatment on the surface, which means it handles the -20 to 200°C range better than some of the oxide-coated stuff you'll see, and round head design that lets you thumb it on or off pretty much without a tool (most buyers appreciate that after a long day).
The quick release mechanism is actually smoother than the old-style collar designs, and we've had these hold steady at 3000 PSI on hydraulic loops for months without a hiccup—that's tighter tolerance than many DIN-rated fittings we've tested.
Lead time is usually 20 days or so for NPT threads in the 1/4 to 1/2 range, but check on BSPP if that's what you need—we carry them but sometimes have to pull from a different stock location. MOQ is 50 units, give or take, for bulk pricing that typically saves you about 15% over smaller orders.
We include the COA with every shipment and teh SDS if you need it, but don't expect these to hold up in high-vibration environments without periodic inspection—the quick release mechanism can loosen over time if not seated fully, that's just the nature of the design.
It's rated for 3000 PSI, so it can handle high-pressure hydraulic and pneumatic systems without issues.
Both NPT and BSPP thread types are available. Just let us know which one you need when ordering.
We usually require a MOQ of 100 pieces per size, but we can discuss smaller quantities for sample orders or first-time buyers.
Yes, we can supply mill certificates for the 304 stainless steel and pressure test reports upon request.
The temperature range is -20°C to 200°C, so it works for hot fluids up to 200°C, but it's not designed for steam applications above that limit.
