With LOCTITE thread sealants preventing costly chronic failures.
With conventional thread sealing methods, pressurized fluids and gas leaks can cause costly downtime. By using LOCTITE thread sealants, joints are able to withstand burst pressure rating of most piping systems, preventing pipe failure. Watch how LOCTITE thread sealants eliminate leaks to enhance the reliability of your products & equipment.
Leaks are a significant and common problem for manufacturing and maintenance professionals. While a certain amount of leakage might have been acceptable in the past, leaks are no longer tolerated in today’s marketplace. Conventional thread-sealing methods can leak and ruin piping systems, which leads to downtime and increases costs.
LOCTITE thread sealants are the preferred solution for many different applications across industries to secure threaded pipes, hydraulic systems, and other connections from fluid leaks. Reliable thread sealing is achieved as the anaerobic thread sealant cures in the absence of air and contact with metal surfaces creating a more reliable fit compared to conventional methods. Thread sealants are ideal for preventing leaks caused by vibration, changing pressures, or changing temperatures. They are the ideal solution to preventing leaks in industrial maintenance and assembly applications due to their ease of application and quick cure times.
The lubricating properties of thread tape may allow for closer fitting of threaded pipe joints. However, it does not eliminate all the gaps which LOCTITE can fill completely.
Pipe thread paste dries up to form a seal between pipe joint threads. However, it shrinks while drying and may not fully eliminate the gaps which LOCTITE can fill completely.
