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)
Specifications

Features & Benefits
- Wide temperature range performance (–73°C to 220°C)
- High oxidative and shear stability under dynamic stress
- Minimal evaporation and low oil bleed at high heat
- Excellent corrosion protection under ASTM D6138 and D130
- Compatible with common elastomers and polymers (Buna-N, EPDM, Viton)
- Hazard-label-free formulation with no intentional PTFE or PFAS
- Supports product consolidation and reduces supply chain complexity
- Ideal for both OEM specification and MRO standardization
Problems Solved
Inconsistent performance under thermal cycling Excessive grease softening during high-shear operation Need for multiple greases across temperature extremes Corrosion risk near yellow metals or in wet conditions Compatibility issues with elastomeric or plastic components
Applications
