• 226 Full Circle Clamp Couplings Single Band o Band: Stainless Steel Type 304. o Lugs: High strength ductile iron ASTM A536. o Tapered Gridded Gasket: Molded tapered ends provide full, uniform sealing at the lap joint through the full O.S. range of the clamp. The finely gridded surface (16 grids to the square inch) provides a network of seals around the damaged area and superior sealing on rough or pitted pipe. Grade 60. Compounded to resist – oil, acids, alkalies, most (aliphatic) hydrocarbon fluids, water and many chemicals. Temperatures -40°F to +212°F. o Bridge Plate: Stainless steel recessed flush and bonded into gasket. o Bolts: Corrosion resistant high strength low-allow steel ASTM A325 or A242 with heavy semifinished hexagon nuts ASTM A563. Optional stainless steel bolts and nuts are Type 304. Stainless steel nuts are Teflon coated to prevent galling. • 228 Full Circle Clamp Couplings for larger diameter pipe o Band: Stainless Steel Type 304. o Lugs: High strength ductile iron ASTM A536. o Tapered Gridded Gasket: Molded tapered ends provide full, uniform sealing at the lap joint through the full O.S. range of the clamp. The finely gridded surface (16 grids to the square inch) provides a network of seals around the damaged area and superior sealing on rough or pitted pipe. Grade 60.

Optional stainless steel bolts and nuts are Type 304. Stainless steel nuts are Teflon coated to prevent galling. • Omni Coupling System – 441 Cast Straight Couplings Cast Transition Couplings 4”-16” o Meets AWWA C-219 Standards o Sleeve: Ductile Iron ASTM A-536. Ends have smooth inside taper for uniform gasket sealing. o Gaskets: Grade 30 – standard – specially compounded rubber of all new materials with ingredients to produce superior storage characteristics, permanence and resistance to set after installation. Recommended for water. Temperature range -40°F to +150°F. o Follower Flanges: Ductile Iron ASTM A-536. Designed for high strength/weight ratio. Thickness determined by coupling size & catalog number. o Bolts & Nuts: Corrosion resistant high strength low alloy steel bolts with heavy semi-finished hexagon nuts to AWWA C219 (ANSI-A21.11) standards. o Finish: Blue shopcoat enamel standard.
