Do you use silicon on the bottom of your tube?

I received my pump with gauge and 1.50” tube to pack and shoot for length. My question is should i buy a silicon sleeve? Or does it matter since i’ll pack it?

I didn’t know if the sleeve was recommend to double as a cock ring to retain blood into the pump or create better plumpness. Or even for comfort.

What do you experience pumpers recommend?

Silicon sleeves are optional, unless:

• you need one for comfort
• you need one to adapt a too-large tube to your size

Thank you for the response. I will go without one unless its needed for comfort. I wasn’t for sure if it made it easier and helped with gains or comfort only. That answers my question thank you.
