Loctite Thread Sealants

Loctite thread sealants, available in liquid form or as sealing cord, prevent leakage of gases and liquids. Designed for low and high pressure applications, they fill the space between threaded parts and provide an instant, low pressure seal. When fully cured, they seal to the burst strength of most pipe systems. Browse their full range below.

Find the right thread sealant for your application.

Loctite offers a thread sealant suitable for any piping system. When sealing metal-to-metal pipe connections and fittings, Loctite anaerobic thread sealants are recommended, as they cure in the absence of air and upon contact with metals. For plastic-to-plastic or metal-to-plastic combinations, Loctite silicone thread sealants or Loctite 55 are the preferred choices.

Thread sealants are available in a variety of forms, from liquid to paste to solid. Each is suited to different applications. Liquids are ideal for flowing into gaps in threaded connections. Pastes and solids are best for overhead applications where it’s necessary to prevent drips, or an instant seal is needed.
