This Victor Reinz Engine Case O-Ring is a direct-fit replacement for Porsche 996/997 applications from 19982026 listed in the fitment table below. This sealing ring helps close a specific service joint where the original rubber can harden, flatten, or leak after years of heat cycling and compression.

Victor Reinz is known for sealing products used in factory and service applications, from head gaskets and valve cover gaskets to molded seals and O-rings. The brands strength is material selection and fitment accuracy in joints where a small leak can create a much larger repair problem.
