This Victor Reinz O-Ring is a direct-fit replacement for Porsche 928 applications from 1978–1987 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.
As a Dana brand, Victor Reinz brings OE gasket and sealing-system experience to service parts for European engines. Their components are built around the demands of heat, pressure, oil exposure, coolant contact, and repeated thermal cycling.
