The Peterson small block Chevy crank seal matches Jesel part SEL37200 and is supplied as a front crank replacement for compatible SBC applications. Peterson seals are intended for engines operating with crankcase vacuum and aim to preserve high vacuum levels to support crankcase management. This makes them well suited to dry-sump setups and other systems where steady vacuum improves oil control.
