Thread seal tape and pipe dope are both effective pipe sealants. However, many people prefer using thread seal tape since it is cleaner to work with than traditional grease or paste-like sealants. Plumber's putty is used to form a water tight seal between the sink and the faucet and between the sink and the drain. Some of our models include gaskets making sealants optional. Plumber's putty is not for use on threaded pipe joints or marble surfaces.
