The Cometic Rotax 600 head and base gaskets (3.860 blank) are designed to require less clamp load while conforming load distribution across the sealing area. This construction helps create less bore distortion and typically removes the need for sealants or re-torquing, delivering consistent sealing behavior suitable for Rotax 600 head and base assemblies.
