The Streamline S-Series is engineered to meet the majority of plant-wide applications with great reliability in service. The S-series goes beyond the basics of fluid sealing to address the economies of total sealing workflow. S-Series will streamline inventory, simplify seal selection, reduce installation complexity and minimize total maintenance costs.

Optimized Design

The S10 Single and S20 Dual Tandem are a matched pair of high-performance, robust seals that make standardization easy.

Interchangeable Parts Between S10 and S20

The S-Series is a complete system with common parts for predictable performance and simplified inventory No other seal family uses parts commonality better.

Unique "cassette-within-a-cartridge" design allows users to swap the S10 for an S20 in a minute. Face materials swap out to match service needs while keeping spares to a minimum.
