Brand doesn’t matter afaik.
They are simple metal parts so they’ll last forever, unlike the plastic ones.
The rubber seals and o-rings are standard parts that can be easily sourced and replaced.
Grease can help seal them, however it also attracts dirt so not ideal.
Only thing you’ll ever have to replace is the little rubber O-rings (I use these at work on the radiator fill ports and they’re genuinely bombproof)
Get some proper reinforced hose and you’ll never need to replace your garden hose / jetwash hose again
