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.
I second this. I also like that the connectors’ interior diameter isn’t smaller than the hose so it doesn’t affect the flow, unlike a lot of other snapping connectors.
Simple, serviceable, quality.
