Single Cartridge with flush S1

The S1 Single Cartridge has become the cornerstone product for Apex Sealing. Since it’s introduction, our goal has been to offer a rugged, well designed stationary multiple spring cartridge at a price that aggressively competes with the older mass produced rotating spring designs.

The success of the S1 has far surpassed our expectations. The seal has allowed both Apex and it’s customers to reach new plateaus of durability, end user satisfaction and profitability.
