Firewall sealant and Fire Safety

Jimzim · #1 05-12-2011, 07:44 AM

Can anyone recommend a source for a firewall sealant that can easily be mixed/dispensed in small quantities? Each time I need a dab, I can use Pro Seal but the shelf life is short and I can't find a small quantity at a reasonable price. What else might be out there? The high temp RTV is only rated to 600 degrees F.

Thanks in advance! Jim

I have used expired proseal on various things. I wouldn't use it in a fuel tank but I used it on my firewall.

Keep your ProSeal in the fridge .... you do have a beer fridge in the shop, don't you? It will last for years. No worries using it for jobs like this.

My plans from vans said use (fuel tank sealant) on skins to seal to firewall flange.

This is what I used. Flamemaster CS1900 Firewall Sealant. Available from several different vendors.

Home Depot sells it in the tube

Ditto for me.

Pro Seal is not a fire barrier, this stuff is.

Pro Seal (for fuel tanks) is NOT a good firewall sealant! I don't know what temp it's good for, but it's nowhere near 600F, and it burns.
Vans sells a firewall sealant, but it's not cheap and has to be mixed as well (maybe that's the stuff you are talking about). I used it to seal my firewall and all the openings I could at that time. The rest got the Hi-Temp RTV.
