Sounds ideal. How deep is the <4g one? My one wot I posted a picture of is 7g, but it's 13mm deep. I appreciate generous threading on a permanent bonded bung.
6mm. 1×D is enough thread engagement. It wouldn't make any difference to pricing to make them up to 12mm thick if that's what you want, but I've been using the 6mm ones for years without problem, and I tighten them to 5Nm after clamping the stem.
