Rubber steel EPDM-KTW
EPDM rubber steel seals (KTW) are applied in water pipeline construction.
Vulcanized EPDM rubbers are mainly used because of their good chemical resistance. Apart from that, EPDM rubber is highly resistant to ozone, ageing and weather.
A steel ring vulcanized in the flange seal absorbs pressure and stabilizes the rubber seal. This makes the rubber seal self-center its outside diameter to the inside diameter of the screw holes (with inserted screws).
Use
- wastewater (sewage plants)
- drinking water
Product assets
- Good pressure absorption due to vulcanized steel ring
- Easy installation due to self-stabilizing construction
- Easy installation due to self-centering function
- Complying with the KTW guideline
- Good chemical resistance
