Tue May 13, 2008 8:46 pm

I am using CB performances fiber gaskets and its dripping dangerously, Both are leaking and i've used two sets of seals. Those fiber gaskets are not working. I torqued them down to where I thought I'd strip the fitting. Would washers work? I figured the threads are probably softer then washers. Anyone have a solution?

Any help??

Thanks

Check local industrial/hydraulic supplier for a Nylon (synthetic) flat gasket...

Or look for what is called a self sealing washer ...

Also check JEGS or SUMMIT or EARLS, they have AN style banjo fittings for Metric carbs (weber-dels), they probably have washers also....

The banjo may be warped. Try flat sanding them, if that does not work replace them.

I like to use loctite 565 on them. It works well. Just a tiny bit.. enough to barely coat the fiber washer. Wipe any excess off and it will seal up nicely as long as your banjo is not screwed up.

Weird thing was, originally it only had a seal at one side of the banjo. With that I know its at least mostly flat. It seeped, but generally held pressure. I called CB and they said the fiber works. Ha, I'd love for them to show me.

Today I bought nylon rings from flaps, so we will see tonight.
Thanks for the help everyone!

There two gaskets one in one out.
I would not use nylon, bad idea! When and not if it splits you will go up in smoke and fire real quick. I have also used soft aluminum and copper gaskets with really good success so maybe that will do it. Replace the banjo's if all else fails.

Early unions use one gasket. The late ones use two. The early ones have a bolt with a 11mm head, the late has 16mm head.

And that bolt uses a copper washer for a gasket at the union on the early ones. Both styles two gaskets.

You know what I mean, don't get picky.

Make sure the mating surfaces are smooth. I have found that tightining the bolt while the gaskets are wet, works for me everytime.

JB WELD EVERYTHING! [reality] Just kidding for those poor suckers that might really try it [/reality]

The loctite 565 is very good. It cleans off easily and seals well. Stinks though. :lol:
