The A-ZN Series Flat Face Couplings utilize specialized plating for high corrosion resistance, designed to exceed the ISO salt spray test. Standard zinc plating is rated for 400 hours before red spotting. The Z version offers higher pressure and superior flow ratings with a lower pressure drop compared to competitors’ products. The ZN version plating is designed to exceed 1000 hours before the appearance of red spotting in the same ISO salt spray test.
