Swim recieved a Sep Funnel and it came pre-lubed. The type of lube is unknown.
Swim wondered if this lube might not hold up under exposure to Tulol, Bestine and or Naptha.
Swim, not wanting to introduce things into his final procuct, thought he would inquire here for answers. Thanks in advance.

wouldn't worry about it. it's inert

i've worked in a polymer lab with such things, with solvents like chloroform, ethyl acetate, hexanes, and diethyl ether. it didn't end up in the product.

Thanx benzyme for your response. I thought as much but wanted to put the question out here.
