Where is the cheapest place to buy these?

I'm sure I paid about 20p last time I bought one back about four years ago.

The cheapest I can find them now is about £1.50 each with free postage from various ebay sellers.

I know that they could be cut from gasket paper, but for the old price of 20p it wasn't worth the effort of doing that.
 
Needed a fine fuel proof gasket for a strimmer and found the card they put under a Ginsters pastie was ideal, its thin, quite dense and seems to be impreganted to make it waterproof. Makes really good gaskets but only small.
 
Thanks for the replies.

I have heard of cutting them from cardboard packaging before. Will that stand up to being exposed to the coolant?

I wouldn't want to waste time fitting something that started leaking again.

While on this subject, the parts diagram also shows an o-ring above the thermostat.

As far as I knew, the earlier type used the paper gasket, and the later type had an o-ring.

Are both supposed to be fitted?

I use milk/wine cartons when stuck down here as postage from UK is bloody expensive...

From memory the o ring goes under the thermostat
 
card gasket will work, smear it with a bit of grease before assembly, makes them last a bit longer, but tbh dont be tight and just buy some gasket paper!
 
I tend to make gaskets to save time, nothing more annoying than being held up for days waiting on a gasket. Fine if its planned maintenance as you can order ahead but a lot of jobs are not. I did my apprenticeship on aircraft and it was part of our training to make gaskets. You were expected to be able to fix the aircraft and get it back in the air not have it stuck waiting on parts you could make.
