So I'm installing a low fluid switch in a custom tank, & was wondering what is the best sealant to use? Urethane? Silicone? A permatex product?

Thanks!

 

If you haven't yet purchased the level switch, you might like to consider this one:

It comes with a EPDM gasket (alcohol resistant). The gasket expands when you tighten the nut and seal the 22mm hole. External fitting.




If you have problem making a seal outlet from a plastic tank, this fitting will help you to do it effectively: (you might need to register):

100% silicone resists alky/meth.

 

Thanks Richard! I actually am using that EXACT level switch, except it is being mounted entirely inside the container. I mainly needed to know what I can seal the container's lid with.. I'll be posting pictures of my mad scientist arrangement in a day or 2, haha.. You guys are gonna think I'm nuts.


Thanks EVE-SLOW! This is going to seal a lid onto the container, so it will not ever be submerged in Meth, but will be keeping it sealed and get splashed with meth all the time.
