Straight coupling nut 4" galvanized M2, NR 2, NR 270 OPAL 270-12V

APPLICATION Cast iron fittings for conveying non-aggressive gases and liquids are used in threaded pipe connections, and in particular in water supply, gas, steam, central heating, sprinkler installations, etc. for transporting non-aggressive liquids and gases. SURFACE / ZINC PLATING Fittings can be supplied according to order with black or zinc-plated surface. According to standard PN-EN 10242, the mass of zinc coating per surface area is greater than 500 g/m2, which corresponds to an average layer thickness of 70 μm. Both black and zinc-plated surfaces are corrosion protected. Corrosion protection does not contain polycyclic aromatic hydrocarbons. WORKING PRESSURE
