Steel flange for 12mm thick head (suitable to become 10mm after relative flattening and not like the classic flanges that can be found on the market from 10mm which becomes 8mm causing venting)
Using this flange it is possible to build manifolds or make jigs - templates for particular manifolds.
It is possible in case you want to modify the flange (different holes, different thicknesses etc) to realize it also on your indication with a surplus of cost and we can supply technical drawing for your eventual modification.
