Straight coupling nut 3/4" black M2, NR 2, NR 270 OPAL 270-5S

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 COATING Fittings can be delivered according to order with black or zinc-coated surface. According to PN-EN 10242 standard, 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-coated surfaces are corrosion-protected. Corrosion protection does not contain polycyclic aromatic hydrocarbons. WORKING PRESSURE
