Overview
The Flex-A-Seal S16315 42ABC.F.22 25250 is a precision-engineered 1-3/4″ bellows assembly constructed with Silicon Viton elastomer materials. This cartridge-style seal assembly is designed for rotating and stationary pump applications requiring dynamic sealing under moderate pressure and temperature conditions. The elastomer bellows design provides flexibility, spring characteristics, and reliable containment of process fluids across a wide range of industrial operating environments.
Key Features
- 1-3/4″ bellows diameter for standard industrial pump cavity sizes
- Silicon Viton elastomer construction for broad chemical compatibility
- Elastomer bellows provides integral spring force without additional springs
- Cartridge-style design enables straightforward installation and replacement
- Operating pressure range suitable for centrifugal and gear pump applications
- New condition, fully inspected and ready for deployment
