Straight coupling nut 2.5" black M2, NR 2, NR 270 OPAL 270-10S

APPLICATION Cast iron couplings for transmitting non-aggressive gases and liquids are used in threaded pipe connections, particularly in water supply, gas, steam, central heating, and sprinkler installation networks, etc., for conveying non-aggressive liquids and gases. SURFACE / GALVANIZING Couplings can be supplied according to the order with a black or galvanized surface. In accordance with the PN-EN 10242 standard, the zinc coating mass relative to the surface is greater than 500 g/m2, which corresponds to an average layer thickness of 70 µm. Both the black and galvanized surfaces are anti-corrosion protected. The anti-corrosion protection does not contain polycyclic aromatic hydrocarbons. WORKING PRESSURE
