Description

The Würth Copper Spray CU 800 is a high-performance anti-seize and lubrication spray designed to protect metal components exposed to extreme temperatures, pressure, and corrosion. Formulated with fine copper particles, it provides a durable protective layer that helps prevent seizing, galling, and rust in demanding mechanical environments.

Ideal for use on bolts, nuts, exhaust systems, flanges, and threaded connections, CU 800 ensures easier assembly and disassembly even after prolonged exposure to heat and moisture. Its excellent temperature resistance makes it suitable for automotive, industrial, and agricultural applications.

This copper-based spray forms a long-lasting protective film that reduces friction and wear while improving maintenance efficiency and extending component life. It is especially effective in high-heat areas where conventional lubricants may fail.

Easy to apply and highly effective, Würth Copper Spray CU 800 is an essential maintenance product for professionals and DIY users alike.
