Compression tester adaptor.

The 12mm adaptor I got with my tester had the wrong thread pitch.

The TC takes 12 x 1.25.

Use the wrong 12mm adaptor and you'll be in BIG trouble, the wrong one starts into the plug hole as if it fits, but slowly gets tighter.
Go tighter still and your spark plug threads Will FUBAR.

I ended up hollowing out a spark plug and JB welding the non-fitting adaptor inside it...
