What size hole saw should be used for a 3" Uniseal?

4" hole saw. The link below has a chart for the various sizes. http://www.unisealshop.com/page.cfm?page=3

What temperature can this withstand, I am considering this for an automotive application and was wondering if it can handle engine bay heat

I used this product for pond plumbing. I don't think this can handle the amount of heat.

Will this work on a 55 gallon plastic drum? (Round side?) Thanks

Yes. It works well when executed correctly.. I have one in a huge tank twenty feet in the air. It has set for seven years and not leaked a drop. It has a four foot hole, and holds 3,000 gallions. Wish that this helps. Uniseal..

What pipe would work with this? a 3-inch pvc pipe has a outside diameter of greater than 3 in and is far bigger than the hole in the uniseal

Uniseals are labeled for the size pipe they work with, This uniseal is designed to work with 3" SCH 40 PVC pipe.
