4 x 3" Shielded Reducing Coupling - Stainless Steel - No-Hub

• Designed to connect cast iron no-hub soil pipe and no-hub fittings compliant with ASTM A888-11 and CISPI 301-09 in above-ground and underground residential and commercial applications
• Easily installed in new construction or repair applications, eliminating the need for labor-intensive hub-and-spigot caulking
• All heavy-pattern worm-gear band clamps are attached to the shield with a rivet through an elongated slot, which not only stabilizes the clamps during the tightening sequence
• But also allows the clamps and shield to move independently, thus preventing uneven clamping force, binding and shield-crimping
• Durable 28 ga stainless steel shields are corrugated, permitting even gasket compression and reduced buckling at the overlap
• Full-pattern neoprene rubber gasket is tear-resistant and internally beaded, to ensure a positive seal and mechanical joint, with greater pull-out resistance
