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: junk - I bought 2, First one came apart and wouldn't pass fuel. Second one wouldn't snap together and the O ring broke, and spilled fuel all over the garage and me. When there is no fuel in the line they work fine, but once there is fuel in line it screws you. What a joke! Don't buy, junk!

## 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/
