Overview
MOLYKOTE® G-5133M Wide Temperature Range Grease is a silicone-based, hazard-label-free solution developed to meet the evolving demands of modern industrial, automotive, and electronic systems. This high-performance grease delivers best-in-class dynamic lubrication across a wide operating temperature range—from cryogenic lows of –73°C to sustained highs of 220°C—making it a direct upgrade over traditional MOLYKOTE® 33 and 44 series greases.
Unlike many conventional materials, G-5133M retains mechanical consistency even under high-shear conditions, exhibiting minimal change after 100,000 strokes in worked penetration and maintaining roll stability with <10% shear-induced softening. With top-tier corrosion resistance (ASTM D6138 rating of 0, ASTM D130 rating of 1b) and excellent compatibility with a wide range of elastomers and polymers, it’s ideal for lubrication points exposed to harsh chemical, thermal, and environmental stress.
G-5133M simplifies inventory and maintenance workflows by consolidating high- and low-temperature grease needs into a single reliable material—without sacrificing performance or safety.
No intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS)
