When the priority is long-term sealing under consistent load, AS oil seal stands out for all the right reasons. Its simple profile belies a dependable performance—thanks to high-grade NBR or FKM construction and a steel-reinforced structure that holds firm under rotation. AS seal is a popular double-lip seal design.
