For a standard 1098 and an A+ 1275.

The same? What size? I'm looking to buy a compression tester as I reckon it will be a handy thing to have around in the long term.

Thanks Matt. I guess that means 14mm, since that seems to be the standard size.

Mihe has a rubber cone on it so it will fit most sizes

most new compression testers come with the standard and small thread size fittings. Mine was dirt cheap and had both, but if you're going for a bargain basement 2nd hand then 14mm it is.
