Insulating Flange Seal to fit Amal Flange Carbs - 26mm (1.00" 16H/ES2 etc)

These insulatings seals are 3mm thick and this item is for an internal bore of 26mm (approx 1"), to fit flange fitting Amal carbs.(i.e. 2.00" between studs).  These thick washers can seal as well as insulating the carb from excess engine heat.. 

Price per each.

Thicker than the paper type carb gasket we also sell (Item 0452/0453) - and less thick than the Tuffnol spacer rings we also offer, these 3mm thick gaskets/insulating seal's provide a gasket face for Amal flange fitting carbs (with 2.00" between stud centrres - which covers most Amal flange type carbs), but can also offer more heat insulation for the carburettor than the plain paper type washer.  These are manufactured by a high quality specialist UK gasket manufacturer .

These are 26mm bore - which is very similar to the normal 1.00" 16H sdievalve engine, and close to the 1 1/16" bore used on postwar Norton 500cc OHV models.  I am supposing this type of gasket/inuslating seal would be useful when running cast iron head/barrels that get very hot in summer months.
