Fel-Pro BS40729 Rear Main Seal
This Fel-Pro rear main seal is a replacement component for engine repair. It fits between the crankshaft and block to prevent oil leaks at the rear of the engine. The seal is supplied new in a transparent finish. Mechanics and DIYers use it during rebuilds or when addressing rear-main leakage.
Suits standard rear-main seal replacement
This part suits anyone replacing a worn or leaking rear main seal on a compatible engine. It is not for builders who need a different seal profile, a rope-style seal, or a complete overhaul kit with additional gaskets. Buyers requiring an integrated housing or a specific material not listed should verify the application before ordering.
Transparent Fel-Pro rear main seal BS40729
The transparent colour identifies this specific Fel-Pro BS40729 seal variant. Confirm that your engine application calls for this exact part number and a transparent seal design. Fitment depends on matching the OE specification for your crankshaft and block machining.
