Reduction nipple narrowing nut 6/4X5/4" galvanized M4, NR 246 246-33V

APPLICATION Cast iron couplings for the transmission of non-aggressive gases and liquids are used in threaded pipe connections, in particular in water, gas, steam, central heating, sprinkler systems, etc. for transporting non-aggressive liquids and gases. SURFACE / GALVANIZING Fasteners can be delivered as ordered with black or galvanized surface. According to the PN-EN 10242 standard, the weight of the zinc coating in relation to the surface is greater than 500 g / m2, which corresponds to an average layer thickness of 70 m. Both the black and galvanized surfaces are protected against corrosion. The anti-corrosion protection does not contain polycyclic aromatic hydrocarbons. WORKING PRESSURE
