Cosworth RB25DET metal head gasket is a high performance gasket
designed to seal under high power under the most demanding conditions.
Cosworth's RB25DET head gasket is available in 87mm bore with a variety
of thicknesses. Each Cosworth RB25DET headgasket features:
Individual die cut layers of stainless steel with superior consistency compared to laser cut gaskets.
Pre-coated stainless steel with a 0.25 micron layer of nitrile rubber
ensures consistent distribution of coating with no high or low areas.
Manufacturing dimensional tolerance of 0.002”.
Die cut manufacturing process ensures smooth edges, unlike laser cut gaskets.
Cosworth gaskets feature a “stopper” sealing layer for additional
torque around each cylinder. The width of sealing area is specific for
each application thereby providing ultimate sealing properties.
