Review: Do not leak, no loss of pressure - I use these in a looped water-cooling system where I have to break the lines occasionally without introducing air (thus avoiding re-priming the system). They are easy enough to take apart and reattach, especially if a little bit of grease is applied (in my case food-safe). They close with a nice audible click to confirm a lock. I have experienced minimal to no air infiltration even when disassembled for an extended period. They are a bit pricey, but are worth it since they are a perfect solution for my application. They are built tough, so should last a long time. I assume the o-ring inside is replaceable, but I hope to never have to find out.
Review: used in a dry suit pee valve - 3/8th diameter works for my application. water and body fluids is what it contacts and it works Pros drop in replacement for dry suit pee valve quick disconnect robust and rugged design, feels and looks like US version works as designed, plus double o ring sealed half price of US version, low cost Cons the catheter end is also 3/8 dia and not tapered, so slightly more work to insert catheter but it fits snug somewhat physically larger than US version of quick disconnect

## Features

- The product has one pairs, one male and one female connectors. Please use them together.
- When the male coupling and the female coupling are independent in a piping system, either of them has a shut-off valve function to prevent liquid or gas leakage and flowback.
- When the male coupling and the female coupling are locked together by the snap ring, the pipeline can be formed into a passage in an instant; when the snap ring is released, the male coupling and the female coupling are automatically separated, both ends of the pipe are closed instantly.
- The temperature range is -40F to 180F.They can handle a vacuum to 120 psi. There will be no leakage or air after it is disconnected. So you need not worry about them leaking gas.
- Suitable for a wide variety area. Such as Beer brewing/CO₂ and O₂ gas line/ Fuel Line/Homefill compressor /floating dip tube/

### ⭐ DO NOT RECOMMEND FOR FUEL
*by W***H on June 26, 2025*

Absolutely horrible for fuel line quick releases on a motorcycle. Stopped the flow of fuel and left me stranded. And they fall apart easily when removing.
