Simering A

Simmering Type A

Type A simmerring is a shaft seal with a single sealing lip and a pressing spring that provides the necessary pressure force to the shaft surface, ensuring tightness. Designed to work under medium and high loads. Effectively prevents oil and grease leaks, while protecting the interior of the mechanism from external contaminants. Made of durable NBR and FKM elastomers, it is used in industrial machinery, automotive, hydraulics, and gearboxes. Simmering Type A is a durable, economical solution for working with working fluids and lubricants.
