Nut-and-bolt reduction 2.5X5/4" galvanized N4, NR 45, NR 241R OPAL 241-42V

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 / GALVANIZATION 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
