Rubber steel NBR-KTW/gas
NBR rubber steel seals (gas admission/KTW-compliant) are applied in water, gas and refinery pipeline construction.
Vulcanized NBR rubbers are mainly used because of their good resistance to aliphatic hydrocarbons, mineral oils, mineral fats, and fuels.
Details
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
- gas
- drinking water
- biogas
Product assets
- Good pressure absorption due to vulcanized steel ring
- Easy installation due to self-stabilizing construction
- Easy installation due to self-centering function
- NBR-admission
- Good resistance to mineral oils, mineral fats, and fuels
