Loctite 574 sealant is best suited for hard metal parts such as ferrous parts and pump housings. Loctite sealants are well known for their oil, water and glycol resistance. They are used mostly in sealing close fitting joints between flanges and metal surfaces. The viscosity of Loctite sealant is thixotropic, and they come housed in 50 ml tubes. These sealants are useful in minimizing the movement of the liquid product once applied to the substrate.
