I have these in my garden connected to a retractable hose reel
and sometimes it falls off when the tap isn't fully turned off and left for a while. I'd like to understand the different types of these .
mine has one O ring but I see some of them have two rings, does this make any difference since leaking is not a problem with one ring.
I was wondering if a brass set would be any more durable but I saw that the connector inside the hose still uses nylon to lock it in
I'm assuming my current one is failing because of the nylon lock on the Orange hose part not holding on properly. The brass one does not seem to fix this problem.
I also see that some connectors have this stop valve inside. What does it do and why do only some connectors have it?
especially when sold as a set only one side has it
