POM material
This quick connector was made of High quality POM(polyoxymethylene).Compared with the PP material, POM has good solvent resistance, oil resistance, weak acid resistance, weak alkali resistance , and also has high hardness and rigidity. Also, POM material is non-toxic. You may use it in many areas.
High quality POM material, SUS302 button，Double Diaphragm check valve，Double EPDM O-ring design. We do our best to control the quality of our products.
Double shot-off check valve
• Both male and female sides was built-in check valves.
• 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.
3 tubing size in L series
• We offer 3 size connectors to choose. (1/4" 3/8" 5/16")
• 1/4"---fit for 6-7mm hose
• 3/8"---fit for 10-11mm hose
• 5/16"---fit for 8-9mm hose
• More choices, more convenient.
Panel Mounting quick connector and Hose connection fittings.
• We offer Panel Mounting quick connector and Hose connection fittings.
• The hose connect fittings were mostly used in pharmaceutical industry/Beer line tubing assembly/O₂ and CO₂ gas line etc.
• The Panel Mounting quick connector were mostly used in Beauty industry，such as quick plug IPL handle connector for colder water circulation.
• Perfect in making wine and beer. Both pieces have a valve that closes when the parts are separate, so you get no leakage from either disconnected hose. Likewise, no contaminants can get in. Such as fruit flies, etc.
•After disconnection, neither end will overflow, which is also suitable for the food and beverage industry
Here are all Hose Connecting Couplers.

3/8th diameter works for my application. water and body fluids is what it contacts and it worksProsdrop in replacement for dry suit pee valve quick disconnectrobust and rugged design, feels and looks like US versionworks as designed, plus double o ring sealedhalf price of US version, low costConsthe catheter end is also 3/8 dia and not tapered, so slightly more work to insert catheter but it fits snugsomewhat physically larger than US version of quick disconnect

Our quick connect linking the water bath to our reactor broke. I ordered a replacement from the manufacturer but the delivery time was 2-3 weeks. I found this product on Amazon and decided to order it since it could be available in a couple of days. I fully expected this product would not work as well as the connector that had broken but figured at least it would keep us operational while we waited for the replacement parts. When the replacement parts finally arrived, my chemist told me that the existing parts were working perfectly fine, were easy to use and that he wanted to keep using them as long as they lasted.

These were more expensive than I wanted to pay but they are exactly what I needed to connect my cooling system to my brewing fermenter. Coolant flows to and from the chiller to a coil inside the tank. The tubing connects to the coil with push on barb connectors. Long story short, everytime I needed to disconnect the fermenter for cleaning, etc. I ended up having to cut the tubing as the tubing simply would not release from the barbs. Now I can disconnect both lines easily and without having coolant leak out all over the floor (these connectors seal when disconnected). I reversed the male/female polarity between the intake and discharge so I now can't mix up in versus out from the pump.

I used this to attach my vacuum hoses to my milling bucket. I love the ease of use.

Items as described, rec'd promptly, well-packed, in new condition. They look like they will work well for my application, but I have not installed them yet.

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!
