Topic: Making your own bowl gaskets: which material to use?

[grumpy]

I need new float bowl gaskets & was going to cut my own from sheets of gasket material.

Those that have done this - what material did you use?
What kind & how thick?

thanks!

I got a packet of felpro gasket material from napa, had blue, grey, and 2 corks, thick and thin. I used the blue material on one set, and the thin cork on another set and haven't had any issues yet, this was 2 years ago.

what thickness do you need?  what about using 3/32" buna cord @ $.13/ft ?

Is that fuel resistant?

I would not do that. Very little money saved when you could have a nice rubber fuel proof gasket from K&L that fits perfect.

If your float  bowl has the spring clip to hold on the float bowl, the gasket thickness is critical or the float bowl could get loose because the clip is not tight. Your house could burn down over a $3.00 gasket?

Is that fuel resistant?

Buna N or Nitrile, is a copolymer of butadiene and acrylonitrile. Acrylonitrile content is varied in commercial products from 18% to 48%. As the nitrile content increases, resistance to petroleum base oils and hydrocarbon fuels increases, but low temperature flexibility decreases. Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -65 to + 275 degrees F (- 54 to +135 degrees C), Nitrile is the most widely used etastomer in the seal industry today. Most military rubber specifications for fuel and oil resistant MS and AN 0-rings require nitrile base compounds.

What Lucky says. And I had cut quite few gaskets. Not worth it for carb bowls.

Just buy some Viton orings the size that people use, they are not that expensive.

[grumpy]

Price isn't the issue.
The point of this exercise is to find / make some that don't react with ethanol.
I don't like leaky bowls.
That buna cord might work, need a way to join the ends, though.
Viton would rule.

I guess I could just buy a few sets of aftermarket bowl gaskets and replace more often...

Somone has done this with Viton orings already, on my VFR #042 viton fit perfectly and it has a few more squared off edges than the cb bowls do. Do a little searchin' and Iam sure someone has the size that worked.
