I would get the thick brass connectors and use metal strap clamps. even with the metal strap clamps you still have to periodiclly retighten. Regardless of the type of hose they work loose. I used RTV or super glue with some sucess at the joints and on the screw threads. IMO the plastic ones arn't worth a dare.

I have repaired a few hoses due to freezing damage. I have not had leak issues with the brass end/hose clamp combo on my Gilmour hoses. I have had issues on a cheaper hose though.

most of the time i don't care if they leak. odds ar ewhatever i hook to the end will have a leaky washer anyway.

but what it have done before is to put silicone on teh end before pushing it in the hose. then clamp it down. never had one of those leak yet.

mmmm, silicone....

I have couple 1/4 inch drive torque wrench tighten them to 20 inch pounds they stay tight for me brass ones. I all most every time get new hose put male brass end on hose they seat to washer better for me.
