Is the E-RX flange rubber expansion joint suitable for use with hot water that contains oil-based anticorrosive agents or oil-laden air?

No. The E-RX flange rubber expansion joint is designed for hot water, cooling water, and hot air, but it is explicitly not suitable for mineral oils, cooling water containing oil-based anticorrosive agents, or oil-laden air. Using it with such media can degrade the EPDM rubber and compromise the jointâs performance. Temperature limits: -40Â°C to +130Â°C (temporarily up to +150Â°C depending on the medium).

Can the E-RX flange rubber expansion joint be used continuously at +150Â°C for long-term applications?

No. The E-RX flange rubber expansion joint is rated for continuous operation up to +130Â°C. The +150Â°C value is specified only as a temporary (short-term) limit depending on the medium, so it is not suitable for long-term continuous use at +150Â°C. Continuous exposure at +150Â°C risks accelerated aging and loss of performance. Use within the stated continuous range (-40Â°C to +130Â°C) or consult the manufacturer for application-specific guidance if higher continuous temperatures are required.

Does the E-RX flange rubber expansion joint tolerate intermittent exposure to mineral oils?

No. The E-RX flange rubber expansion joint is not suitable for exposure to mineral oils. The product description explicitly states it is designed for hot water, cooling water, and hot air installations and is not suitable for mineral oils, cooling water with anti-corrosive agents containing oil, or oil-laden air. Continuous or intermittent contact with mineral oil can degrade the EPDM inner and outer layers and compromise performance and service life.
