Victor Reinz Upper Throttle Socket O-Ring for Porsche 911/930/964 (1978–1994)

This Victor Reinz O-Ring is a direct-fit replacement for Porsche 911/930/964 applications from 1978–1994 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 brand’s strength is material selection and fitment accuracy in joints where a small leak can create a much larger repair problem.
