View Full Version : RTV Gas Seal?

I have a good start on making some auminum flanges for an aluminum gas tank.

The basics are, one flange inside and one outside with the filler plate/neck adapted to the outer flange with studs and nuts.

The inside and outside flanges will be held together with a separate group of FH stainless allen 1/4-28's.

I want to seal the thread area where the FH allens go through the outer flange, then the tank's upper surface and into the inner threaded flange's threaded (12) holes.
The flanges proper will have a suitable gasket.

Seems like there ought to be an RTV that will do the job.

Recommendations?

anything except rtv!

used to be that Chevy used fiber washers on the sending unit screws.

I agree. RTV is much too often looked upon as a cure-all. It is not, by any means. It has it's proper uses but they and it's limitations are largely ignored all too often.

I knew that RTV had it's problems around gasoline, but thought if it was used as a thread sealant it may work.

So what should I use?
Keeping in mind I want to be able to disassemble the flanges later on if necessary.

as far as i know , the only stuff that will seal and hold up to gasoline is Permatex

it's worked for me for 40+ years..and many others since 1909

Silicone works great,until it comes in contact with gas.

There should be some liquid Teflon sealer available.

So if I read this correctly your just looking for something to prevent gas from "wicking" up the threads and giving off fumes?

Wouldn't a properly fitted gasket "squish" enough to form a tight seal to the bolt shanks right as they come thru the tank...thus making additional sealing of the actual threads redundant?
If your doubtful, could you add tight "O" rings around the threads of the machine screws or do you figure they would tear?

a drop of oil would keep orings from tearing, most likely.

or use Holley bowl screw gaskets

RTV works GREAT!.....

I believe RTV is the bane of the true mechanic. It is an evil foisted upon us by OEMs in search of a cheaper way to do things.

RTV Silicones jelly in the presence of petroleum products - gasoline nearly instantly, but even oil over a relatively short period of time.

Use it near water only...and then as sparingly as you can.

I'll second permatex #1 as the sealant of choice near gasoline - it won't fix leaks, but it would serve your purposes well.

I'm thinking tank sealer or varnish might work.
Anyone got an opinion on them?

Seals All works great for anything that comes in contact with gas, water or oil. Depending on your application, this will prevent leaks or stop them quickly with great durability. Just don't heat this stuff or it's really difficult to remove...

Here's a review on it....

FWIW, if you test this stuff out, you're only out $2 if you hate it and you'll probably find other uses for it.

I've tried this stuff - it's garbage in my opinion. Others may have luck with it - tried to use it to seal up minor oozing around sending unit - no luck. Tried it around a filler neck seep - no luck. Garbage.

windshield urethane works.....
not sure you'll get the screws back out though...

I used to work at a major oil company research center, next to a refinery. To seal up stainless fittings, and other hard to seal joints, in the presence of gasoline, we used to use a product called "Gasoila". Never used anything better for this application. Hard to find, though.

You'd think it would and apparently it does ok for some, but I think the problem I had with the leaking fuel cell and aluminum tank was that the inner ring with studs welded to it had several poor quality welds that allowed fuel to seep up the threads and out from under the washers on the bolts.
Not to mention that two of the studs on the new aluminum tanks inner flange were welded in at an angle so not too many things will seal with an angled hold down stud.

The studs are effectively 'under-water' when the filler neck is full and gas runs out pretty good.
After the fuel level goes down, fuel sloshing around does the "wick-up" bit as HackerBill mentions.

I thought of o-rings around the studs/bolts and it would be easy to machine a shallow step where they go, but I think using a double flange setup with sealant laden bolts into the lower flange will work better.
That way, the filler neck's flange only has to seal against the outside tank flange for a good seal.

Fwiw, the inner flange will be two piece and seal for a full 360 degrees.

With a gasket, fuel shouldn't get near the filler flange/outer flange studs to leak.

Just another one of the 'good ol daze' universal type parts that take some massaging to work right.
Kinda what a great part of hot rodding was back in the day.

A pair of good rat-tail files was on the workbench of every serious hot rodder I ever knew.

I'll shoot some pics as I go and post it as a tech article.

If it helps one person I'll be amply rewarded.

Hell, if it works for me I'll be happy....:D

how about a sketch of the cross section of this thing? my imagination isn't working as well as it should be

I didn't know this stuff was still made!
IT's MARVELOUS!!!!
I had some that I inherited from my Dad who I think inherited from his but it finally ran out and I haven't seen it since.
The one I'm familiar with I think is the hard set.
It was used for those problem areas n old carburetors that we figured would mever have to come apart again, by us anyway... ;)
Get some...I'm going to.
