890-I42 Closet Flange, 4 In Cast Iron/Neoprene/Stainless Steel

A closet flange (also called a toilet flange) is the critical connection between your toilet and the drainage system in your home. The Sioux Chief 890-I42 is a 4-inch cast iron closet flange designed to provide a secure, watertight seal that prevents leaks and keeps your toilet stable. Whether you're installing a new toilet or replacing a damaged flange, this heavy-duty component ensures your bathroom plumbing functions reliably for years to come.

Cast iron construction makes this flange exceptionally durable and built to withstand daily residential use. This compression-style flange fits 4-inch cast iron DWV (drain, waste, vent) pipe connections. The internal neoprene compression gasket, tightened via three stainless steel bolts, creates a watertight seal that prevents leaks from the drain system.
