The Chevy Block Adapters Part #200 uses three O-Rings that seal the adapter against the block and bolts in place of the stock filter adapter. Two O-Rings create a double seal which stops oil from leaking outside the engine. The single inside O-Ring seals the inlet from the outlet opening. All Block Adapter have machined O-Ring grooves to keep O-Rings in place so they don’t blow out or leak. Chevy Block Adapter O-Ring Kits also include the two small O-Rings used around the Mounting Bolts to seal them from leaking. All O-Rings are made of Viton® which is heat, chemical and fuel resistant.
