Chesterton’s Inflatable Safety Seal™ is a pneumatic inflatable seal used for static shaft sealing. Used in conjunction with a mechanical seal, the ISS is designed to act as a static seal in the event of unacceptable primary seal leakage and as an interim seal during primary seal rebuild.

The overall system is quite robust and adds an element of security and flexibility to any sealing application. The Chesterton Inflatable Safety Seal can be provided to seal a wide array of shaft sizes and to fit most any equipment bolting pattern.

A staple of Chesterton’s sealing program, the ISS provides a level of convenience, security and safety that none of these applications should operate without.
