SMITH-BLAIR's421 Top-Bolt® Wide Range Coupling is easy to install with only one bolt to tighten on each end. The coupling features a removable inner gasket for larger O.D. sizes. The inner gasket is also bi-directional and can be reinstalled if needed to accommodate the various sizes you are working with.
The 421 features a corrugated armor plate that reduces friction between gasket and armor, allowing better gasket seating and prevents armor from gouging the flange coating. The coating is Smith-Blair’s corrosion resistant Flexi-Coat® Fusion Bonded Epoxy.
The Top Bolt is easily disassembled and has anodes that are available for additional corrosion protection. For more information and specifications, visit Smith-Blair.com
