Pipe and thread sealants from H.B. Fuller.

H.B. Fuller's liquid thread and pipe sealants are specifically designed to seal and secure metal pipes and fittings by filling the space between threaded metal parts and hardening to prevent leakage.

They do an excellent job of sealing in severe environmental conditions and prevent leakage that may be caused by vibration loosening, damaged threads, or temperature cycling. Our liquid thread and pipe sealants seal instantly to moderate pressures, and when fully cured, they seal to the burst strength of most piping systems. They resist a wide range of chemicals, such as hydraulic fluids, oils, fuels, water, lubricants, etc. They are ready-to-use, single-component, solvent-free materials, designed to handle both low- and high-pressure applications. H.B. Fuller’s thread and pipe sealants do not shrink, shred, tear, or relax. They are formed-in-place sealants conforming to the parts they are used on, creating a durable, positive seal. Our thread and pipe sealant family of products offers a full range of viscosities, strengths, and cure speeds that are designed to meet your specific application requirements.
