At Robar Industries, we manufacture some of the best expansion joints in the water industry. A Robar expansion joint is meant to be used for piping, gas, oil, water, and chemicals. Specifically, our expansion joints work best on steel pipelines where the large longitudinal movements of a pipe are concentrated. This pipe expansion joint can be expanded by the installer to 36-1/4 inches in length or contracted to 26-1/4 inches. Read our expansion joint spec sheet for more details or contact us to ask questions or place an order.
