Loctite Pipe & Thread Sealant Paste


The Loctite grey 100ml pipe and thread sealant paste is moisture curing silicone. It is made of silicone and cures on exposure to moisture in the air to form a tough rubber gasket. The nature of Loctite SI 5660 reduces the migration of liquid product after application to the part. It is designed especially for gasketing applications where good resistance against oils and coolants is required. Typical applications include transmissions and cast metal housings. This product has leading health and safety features. This Loctite ready-to-use flange sealant is ideal for flanges with long-term water or glycol contact.
