Is the E-RP Flange Rubber Expansion Joint for Flexible Piping Connections suitable for drinking water and seawater applications within its -40°C to +90°C operating range?

Yes. The E-RP Flange Rubber Expansion Joint for Flexible Piping Connections is described as suitable for drinking water and seawater applications within its operating range of -40°C to +90°C. Its inner layers of butyl rubber (IIR) and EPDM, EPDM outer cover, and reinforced nylon cord provide chemical and environmental resistance appropriate for cold and hot water, pool water, seawater, and drinking water. It is rated for continuous operation -40°C to +90°C with short-term resistance up to +120°C (depending on medium). Note the product is not suitable for mineral oils, oil-containing cooling water, oil-laden air, or systems with constant working pressure above 10 bar.

Can the E-RP Flange Rubber Expansion Joint for Flexible Piping Connections be used with hot water or in systems briefly reaching up to +120°C?

Yes. The E-RP Flange Rubber Expansion Joint for Flexible Piping Connections is designed for hot water and can tolerate brief excursions up to +120°C. Its normal operating temperature range is -40°C to +90°C, with short-term resistance up to +120°C depending on the medium. Ensure the medium is compatible (e.g., hot water, pool water, seawater, drinking water) and avoid mineral oils, oil-containing cooling water, oil-laden air, or applications with constant working pressure above 10 bar.
