Pop open gas cap gasket

[JJHStang]

I posted this before asking for help. I received a lot of good advice. I even replied to one yesterday but don’t really know how the replies work.

I decided to make my own. I found 3/32” thick neoprene 12” x 12” sheet on Amazon for less than $5. My existing gasket measured 3/32” using a multimeter. Found that the diameter of a can of soup is just slightly larger than 2.5”. I marked it on the sheet of rubber and cut it using a exacto knife. Then found a socket that was an inch diameter used it for measuring and cutting the center hole. Not perfect but it seals very well. I stretched the rubber around the center and with a thin flathead screwdriver push under the lip.

I did attach pictures but will not do it again unless someone wants.

Just click on "reply" button. When the new page opens, place curser below the box as you see and type your reply.
As for pictures, we LOOVE pictures, post all you want. Click "attach files" select your pics and post. I'm sure that is self explanatory though.
Hope the neoprene works, let us know after it's been in use awhile.
Good luck.

I wonder if that material would work to make front grill mounted turn signal light socket gaskets?

As long as it is closed cell material. Open cell mat'l will saturate.

 

[Steve McMahan]

Well, it’s a rubber sheet. Isn’t that defacto closed cell?

Neoprene can be either. I looked at the Amazon product, and it doesn't specifically say, but from the description I think it's probably closed cell (states that it gives good oil resistance).

If it has a 'skin' on it, probably. Always worth checking when ordering.

Yea, that Amazon cited source is silent on that. Thanks.

Yeah, if the seller doesn't fully describe their product, who knows.
If it's cheap enough, buy a sheet, cut a bit off and soak it (water or gas depending on intending purpose). If' it's not good, you can still use the rest for something else
