Set of 4 Misab integral oring plates rubber mounts and steel cups to mount twin side draughts. Fits all sizes from 38m to 50mm Dellorto and Weber. Sold as set of four. Integral o’rings last longer then individual o’rings and are a benefit if having to change carbs; fuel expands the rubber o’rings and they can be hard to refit. These will save you time at Parc Ferme!
