Basically, these Q40 couplings solve the problem of hoses leaking at high presure in tight lab setups where you can't afford downtime—it's a really common headache with cheaper connectors.
working pressure hits 120psi or 8.3 bar, which is better than most quick disconnects at this size, and the temperature range goes from -40°C up to +82°C so you can run hot fluids or cold solvents without issues (usually within those limits, anyway).
Tube sizes are 6.4mm, 7.9mm, or 9.5mm, and the thread interface is 1/4''-18NPT—pretty standdard for medical gear—but what a lot of people don't realize is the shell material matters more than the seal choice for chemical resisance in PP/POM over long use.
Most buyers go with the EPDM seals for general lab work, but we've also got FKM and NBR options if you're pushing something aggressive like ketones—that EPDM won't hold up there, and we'll tell you straight up if a seal's wrong for your fluid.
It's autoclavable, though we recommend confirming cycle parameters—20 minutes at 121°C is typical, but we've had customers push 30 minutes or so and it held fine, so you've got some margin (check lead time for custom colors, by the way).
We usually stock these in bulk orders of 50 units or so, and the COA covers pressure test results batch-to-batch, so you're not guessing if that 120psi rating actually holds—it's tighter tolerance than what you'd get from generic import couplings, and that's why labs come back to us.
The Q40 series comes in three tube sizes: 6.4mm, 7.9mm, and 9.5mm, so you can pick the one that fits your setup best.
Yes, we offer custom color options in addition to the standard colors. Just let us know your requirements when ordering.
The Q40 series complies with medical and laboratory equipment standards. We can provide material certifications and compliance documentation upon request.
Yes, the Q40 is autoclavable, but you should consult with us for specific sterilization parameters to avoid damaging the seals or shell material.
Our standard MOQ for the Q40 series is 100 units per size and seal type, but we can discuss smaller quantities for sample or trial orders.
