DRAIN SEALS

Help prevent water leakage in retrofit drain installations. These drain seals are made from a combination of nylon and EPDM Rubber, allowing them to be compressed for a secure fit between roof drain stems and existing plumbing. The flexible rubber expands when tightened with stainless steel screws, effectively stopping water leakage at the connection in case of water backup in the drain.
