PIPE LEAKS? LOCTITE® THREAD SEALANTS ARE THE SOLUTION

Pipe and fluid fitting leaks can bring operations to a standstill. LOCTITE® thread sealants are the preferred solution for many applications across industries to secure pipes, hydraulic systems, and other connections from fluid leaks. LOCTITE® has long been a trusted brand for adhesive and sealant technology, helping customers eliminate downtime and reduce costs.

LOCTITE® thread sealants achieve a tight seal as the anaerobic thread sealant cures when there is an absence of air, and it comes into contact with metal surfaces. It’s ideal for preventing leaks created by vibration, changing pressure, or changing temperatures. Their ease of application, quick cure time, and cost-effectiveness make them the ideal solution in industrial maintenance and assembly applications.

Moreover, LOCTITE® thread sealants do not creep, shrink or contaminate systems. They are a dependable replacement for tape, putties, pipe dopes and paste sealants, and also protect threads and fittings against corrosion. They’ve been developed to withstand a wide range of temperatures and pressures and are available with potable water and gas approvals.

WHEN SHOULD I USE A THREAD SEALANT?

Thread sealants are used wherever threaded parts require filling in order to maintain both low- and high-pressure seals within liquid and gas piping systems. They are integrated into systems within chemical processing plants, petroleum refining facilities, pulp/paper factories, waste treatment centres, and textile manufactories, as well as being used in a broad range of utility plumbing applications. LOCTITE® thread sealants ensure superior sealing up to the burst pressure rating of most pipe systems when fully cured.

PIPE CONNECTIONS

Anaerobic pipe sealants are used within a broad range of industrial plant applications, during both installation and subsequent repair and maintenance. Sealing all types of metal tapered pipe threads, fittings, and connections, the LOCTITE® range of anaerobic pipe sealants are used effectively within highly demanding environments such as the chemical processing, oil & gas refining, pulp/paper, waste treatment, textile, utilities/power generation, marine, automotive, gas compression and distribution industries.

HYDRAULIC SYSTEMS

Hydraulic systems require superior thread sealants designed to work at high pressures. LOCTITE® thread sealants are designed to function under significant stress from environmental factors, delivering durable sealing during assembly and maintenance of hydraulic systems. Used within hydraulic hoses and stainless-steel pipes and fittings, they are also designed not to clog filters or otherwise contaminate hydraulic fluids like traditional putties, pastes, and PTFE tapes.
