Description
Aquatherm 9793815718 2" Polypropylene Coated Flange Ring
Aquatherm is transitioning the flange rings (backing rings) from the powder-coated steel to an overmolded Polypropylene with steel insert ring. This provides significant improvement in corrosion resistance and performance in harsh/corrosive environments. The over molding process results in a slightly thicker ring, so as to ensure the strength and rigidity of the steel ring insert. The Aquatherm bolt kits and bolt length charts have been updated to include longer bolts where applicable (Table 1). However, existing bolt kits will also work with the new rings but may have fewer threads exposed once installed (Figure 1). Backing rings are light gray color for sizes up to 12-inch and black for larger sizes.
