Pump connector are universal?

Hi guys, like the title, I want to know if the pump connectors are universal or if every brand has its own dimensions.

I’m asking this becasue I’m thinking about buy a cylinder from one site (kaplan) and buy the silicone tubing and the pump connector form an other site (thickwall).

Thanks for your time.

Yes, the connectors are universal. You can mix and match.

Thanks Gprent
