Dow Corning 1597418, High Vacuum Silicone Grease, 150g Tube, White/Translucent
Dow Corning 1597418 High Vacuum Silicone Grease, 150g Tube, White/Translucent
The Dow Corning 1597418 is a non-melting, low-volatility silicone grease engineered for high-vacuum sealing, O-ring lubrication, and precision lab equipment — rated from -40°C to +204°C. Its stiff, stable consistency resists a broad range of chemicals and holds up across extreme temperatures, making it the go-to choice for O-rings, plug valves, pressure systems, and laboratory glassware.

Key Features & Benefits
- Non-Melting Formula — Maintains consistent grease body across the full temperature range; will not flow or migrate under heat
- Low Volatility — Minimal evaporation loss even in high-vacuum and elevated-temperature environments
- Broad Chemical Resistance — Resists water, mineral oils, common gases, methanol, ethanol, acetone, glycol, and glycerine
- Reduces Wear — Protects plastic-to-metal and rubber-to-metal contact surfaces from friction and abrasion
- Wide Temperature Range — Reliable from -40°C to +204°C for both cryogenic and high-heat applications
- Dispersible for Cleaning — Can be removed using kerosene, Stoddard solvent, benzene, toluene, ethyl ether, or petroleum ether
Typical Applications
- High-vacuum system sealing (flanges, stopcocks, ground glass joints)
- O-ring lubrication and sealing in pressure systems
- Plug valves and control valves in chemical processing
- Water treatment equipment seals
- Laboratory glassware joints and stopcocks
- Rubber and plastic component lubrication in industrial assemblies
- High-temperature bearing and seal lubrication
Frequently Asked Questions
Is Dow Corning 1597418 safe for use with rubber O-rings?
Yes — it is specifically formulated for rubber-to-metal and plastic-to-metal contact and is widely used for O-ring lubrication and preservation in vacuum and pressure systems.
What is the temperature range of this grease?
It performs reliably from -40°C to +204°C (-40°F to +400°F), making it suitable for both cryogenic lab applications and high-temperature industrial use.
Is it compatible with solvents?
It is insoluble in water, methanol, ethanol, acetone, glycol, and glycerine. It can be dispersed (for cleaning) in kerosene, Stoddard solvent, benzene, toluene, ethyl ether, or petroleum ether.
Can this be used in food-contact or cleanroom environments?
This product is not NSF-rated for food contact. For cleanroom use, verify compatibility with your ISO classification requirements before use.
What size does this come in?
