How to seal a 2.25 leluv pump? Air leaks everytime

[flotation]

What kind of ring/seal will I need for a 2.25 I want to use it for my balls and cock at the same time. Will the juicy xl be enough? Or what else could I go for?

With everything in a 2.25 it should seal itself.

You won’t get a an XL in a 2.25” tube.

Have you mistyped the number?

I'd suggest if you're not holding a vacuum, the first thing to look at is the connector - is it tight enough and/or does it need a new O-ring?

Shave hair around cock and use lubricant on seal as well before tubing.

First make sure you have warmed up sufficiently.
Everything should hang loose before going into the tube.

Grease cock and balls well. Also get areas above the cock and around the balls. These areas will create the seal when suction is applied.
When you start pumping press the tube into your cock and balls until a seal is achieved.
