Overview
Rocker cover gasket Honda 12341R40A00 seals the joint between the engine cylinder head and the upper valve cover.

Original equipment part number 12341R40A00 features exact OEM dimensions with a profile thickness of 6.5 mm and an overall perimeter length of 1120 mm. Weight is 85 g. The molded elastomeric seal maintains flexibility down to -40 °C, retaining its cross-sectional shape and elasticity under repeated thermal cycling without hardening or cracking.
