Plumbing putty is a type of sealant used in plumbing applications to create watertight seals. It is a soft, malleable substance that can be easily shaped and molded to fit around pipes, fixtures, and drains. Typically made from a mixture of clay and other materials, plumbing putty is ideal for sealing joints and preventing leaks. This putty is often used in conjunction with sink drains, faucets, and other plumbing fixtures. Unlike caulk, it remains flexible and can be removed easily when repairs are needed. It is important to note that plumbing putty should not be used in areas exposed to water pressure, as it is not designed for that purpose.
