Description

Corrosion Block Grease is designed to provide maximum protection under severe conditions. Its formulation provides both high and low-temperature performance, increasing the service life of critical components. Corrosion Block Grease strongly resists water wash out and provides superior protection against rust and corrosion.

Corrosion Block Grease outperforms lithium and most synthetic greases and meets or exceeds requirements for NLGI Service Classification GC-LB (automotive wheel bearing and chassis lubricants), which is based on ASTM D4950 performance requirements.
