Is the E-WH flange rubber expansion joint safe for use with potable water or only for food media and oils/fats?

The E-WH flange rubber expansion joint is not safe for potable (drinking) water. It is specifically designed for food media, including those containing oils and fats, and is explicitly stated as not suitable for drinking water. Construction details supporting this: inner layer of white NBR (nitrile) rubber, nylon cord reinforcement, outer CR (chloroprene) rubber, and galvanized carbon steel flanges. It is also marked on the sleeve with a white stripe to indicate its intended use. Operating temperature range: -20Â°C to +90Â°C (temporarily up to +100Â°C depending on the medium).

Can the E-WH flange rubber expansion joint withstand continuous exposure to temperatures up to +100Â°C depending on the medium?

Yes - the E-WH flange rubber expansion joint is rated for continuous operation from â20Â°C to +90Â°C and can tolerate temporary exposure up to +100Â°C depending on the medium. Continuous exposure at +100Â°C is not guaranteed; the +100Â°C condition is specified as temporary. Use within the listed continuous operating range (+90Â°C) is recommended, and for prolonged or critical service near +100Â°C consult manufacturer guidance and verify compatibility with the food media, oils/fats, and materials (white NBR inner layer, CR outer, nylon reinforcement, galvanized flanges).

Is the E-WH flange rubber expansion joint marked for use with food media that include oils and fats only, and how is it identified?

Yes. The E-WH flange rubber expansion joint is specifically designed for installation with food media, including those that contain oils and fats, but it is not suitable for drinking water. It is identified by a white stripe marked on the sleeve. Construction details supporting this use: inner layer of white NBR (nitrile) rubber, nylon cord reinforcement, CR (chloroprene) outer layer, and galvanized carbon steel flanges. Operating temperature range: -20Â°C to +90Â°C (temporarily up to +100Â°C depending on the medium).
