Seal Vent Pipe through Floor

[thinktankair]

What do I use to seal the gap between the vent pipe and the floor of my 1961 Bambi. The gap is small, but it needs a seal of some type so I don't have "things" crawl up through the inside of the belly pan.

Any ideas on this one?

Vulkum (Trempro 635) is a great all purpose sealant. Stick to just about anything and remains flexible. You can buy it from Vintage Trailer Supply, Out of Doors mart, or Inland RV. Some folks have had luck finding in the big lumber stores (Home Depot, Menards, etc.).

I use the expanding foam sealers like Great Stuff around pipes. Since you won't likely use the whole can you can clean the dispensing "hose" with lacquer thinner. The spray cans of Walmart carb cleaner appear to be just lacquer thinner and are good for clean up.

Excess foam can be cut away after it sets up

Thank you Rick and Munno!
