Liquid-O-Ring is an industry leader with a reputation for providing high-quality products and unrivaled service to our customers.

Performance
HT-1800 Pure Copper Anti-Seize is built for the jobs that demand more. Its higher copper content creates a denser, tougher lubricating film that stays stable in storage, won't run on hot surfaces, and holds strong under extreme heat and torque – yet breaks out cleanly every time.

Protection
HT-1800 forms a tough copper barrier that prevents galling, seizing, corrosion, and metal-to-metal contact across any threaded connection or surface exposed to extreme heat and pressure. From daily drivers to diesel trucks, marine, farm, and heavy machinery – it protects what matters.
