This 6" x 5" ductile iron flanged coupling is designed to provide a secure and flexible connection between pipes of varying diameters. Constructed from high-strength ductile iron, this coupling offers exceptional durability and long-lasting performance. It features Styrene Butadiene Rubber (SBR) gaskets, making it ideal for water and sewer service. With high-strength, low-alloy steel bolts and nuts, along with optional stainless steel variants, it ensures reliable connections in demanding environments. Additionally, the coupling's cast parts are coated for corrosion protection, with options for fusion-bonded epoxy and other protective coatings available.
