Thread Sealant

Thread sealants, available in liquid or stick form, prevent leakage of gases and liquids on metal pipes and joints.

Thread sealing is achieved as the anaerobic adhesive cures when confined in the absence of air, and between close metal fitting surfaces. This technology is ideal for joints, which are considered to be dynamic due to vibration, changing pressures or changing temperatures.

Designed for low and high pressure applications, thread sealants 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.

Typical applications for thread sealants include sealing metal tapered pipe threads and fittings in the chemical processing, petroleum refining, pulp/paper, waste treatment, textile, utilities / power generation, marine, automotive, gas compression and distribution industries. Thread sealers are also recommended for industrial plant, fluid power systems.
