Great product, but customer returned contaminated parts. Suggest you find alternate supplier
The product by John Guest is fantastic, deserving five stars. BUT -- someone returned some of these connectors after using them for a strong-smelling oil, maybe car deodorizer. Could not get the stuff washed off my hands after opening the first package. Planned to use this on a drinking water line, but not with this contamination. Got a free replacement with the same problem. Giving up and buying elsewhere. In the attached photo, note the smeared printing on the package. The oil dissolved the package label. Nasty stuff.

Excellent option never thought this could be a solution. So easy to install, I spend a few days monitoring for a leak and nothing. I would recommend this for sure
