Affordable, reproduction version of the red rubber seal for the tappet chest cover on the back side of the engine. This version is more difficult to fit than the Payen version, but works okay once installed. Two (2) required, sold each. Ref: 12A1175, 12A1175E, 12A1175EVA.
Early, flat tappet covers require 12A1139B cork gasket.
If you are looking for a valve cover gasket, see GUG32VC. While these two gaskets are similar in shape, they are not interchangable!
