Is the T-EPDM flange rubber expansion joint safe for use with drinking water and does it have relevant certifications?

Yes. The T-EPDM flange rubber expansion joint is safe for use with drinking water and holds the relevant certification: it has a PZH certificate for drinking water. Its inner layer is EPDM rubber (suitable for potable water), reinforced with a nylon braid and protected by an outer EPDM rubber layer. Designed for hot and cold drinking water systems (and other media listed), it must not contact oily substances. Operating temperature is up to +100Â°C depending on the medium.

Can the T-EPDM flange rubber expansion joint withstand seawater and treated cooling water without corrosion or degradation?

Yes. The T-EPDM flange rubber expansion joint is suitable for seawater and treated cooling water. Its EPDM inner and outer layers resist seawater, chlorinated and treated cooling water and many chemicals; it holds a PZH certificate for drinking water, indicating suitability for potable and treated waters. Operating temperature up to +100Â°C (depending on medium) covers typical cooling-water ranges. Note: flanges are galvanized carbon steel-galvanization provides corrosion resistance but may be vulnerable in long-term seawater exposure compared with stainless steel; avoid contact with oils. For prolonged marine use or highly aggressive seawater conditions, consider flange corrosion mitigation (coatings, cathodic protection, or alternative flange materials).

What media should be avoided when using the T-EPDM flange rubber expansion joint?

Avoid media that contain oils, greases, petroleum products, or any oily substances. T-EPDM flange rubber expansion joint is designed for hot and cold water, treated cooling water, drinking and industrial water, chlorine solutions, glycol, acids, bases, lime milk, esters, ketones and seawater; it must not come into contact with oils or oily mixtures, which can degrade the EPDM inner and outer layers and compromise the jointâs performance. Also avoid aggressive hydrocarbons, mineral oils, silicone oils, and heavy lubricants. For any borderline or mixed media, consult manufacturer compatibility data before use.
