Victor Reinz Engine Oil Return Tube O-Ring for Porsche 911/930/964/993 (1965–1998)

This Victor Reinz O-Ring is a direct-fit replacement for Porsche 911/930/964/993 applications from 1965–1998 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 sealing components are made for the demanding surfaces and temperature swings found in European engines. With Dana’s OE background behind the brand, these parts are selected when fit, material quality, and sealing consistency matter during Porsche service work.
