Coated with ArmorTek™
MasterSeries® backflow assemblies are built with a stainless steel check valve and internals, and coated with ArmorTek advanced coating technology for 6x less surface rusting – making service calls a breeze. ArmorTek is made of an anti-corrosion primer, a microbial inhibitor to limit microbial-induced corrosion, and a protective epoxy-polyester topcoat for maximum durability.
