The choice of material depends directly on the medium being conveyed and the operating temperature.

• EPDM is the first choice for rubber expansion joints in heating, HVAC, and drinking water systems, as it is resistant to water, hot water, and dilute acids up to approximately 150 °C.

• NBR is suited to oil-containing media such as fuels and mineral oils and is preferred in the oil and gas industry, while Neoprene represents a reliable all-round option for general industrial applications and seawater systems.
