Quick vacuum line question

[sitesbyjoe]

I've been swapping out the ok original vacuum line for the cool new red silicone lines.

Up until this point I've just been pushing them on by hand but now that I'm done the "easy" ones I'm wondering if anyone would suggest a particular tool to make sure I get the new ones on nice and tight.

Anyone?

just slip them on with your fingers. Don't lubricate them either. Silicone tubing seals excellently. No tool is needed nor has been invented.
