Get a what we call here is a delta extension 12′ …has one male and one female fitting to extend a flex supply. Cut off the crimps and pull off the ends. Now ya have a female and male end. Attach ends to hose and just screw together…no tools necessary…and absolutely no leaks. I do remove rubber seal and use a gas proof oring. I distain any other existing connector and will never use anything else.
..fyi…1/2 pex crimps work great for 3/8 rubber hose.
