S-Flex II Rubber Expansion Joint System

The S-Flex II® rubber expansion joint system uses the same proven “S” shape design of the original S-Flex® but with approximately one half of the bulb. By making one side flat, we improved the overall sealing capability and further reduced the susceptibility of air-in-leakage.

The S-Flex II® rubber expansion joint system is primarily used in new construction as an OEM component of the steam surface condenser, but Day & Zimmermann can also custom design it as a retrofit for replacing an existing failed metal bellows type system or rubber “U” joint design. The S-Flex II® rubber expansion joint system is custom engineered and designed for each specific application and will accommodate any unique challenges.
