Series SJ-221

Products > Rubber Expansion Joints > Series SJ-221

The SJ-221 expansion joint features a unique arch design which provides greater movement capabilities without increasing face-to-face requirements. The single arch SJ-221 provides the same movement capabilities as a traditional double arch design, while the double arch SJ-222 is equivalent to a quadruple arch product. This design also increases the flexibility of the joint, resulting in lower spring rates. This means less stress on adjacent piping system components
