Frequently asked questions
What makes Corning vacuum grease suitable for low-pressure applications?
The formulation has extremely low vapor pressure, preventing outgassing that would compromise vacuum integrity in sealed systems.
Can this grease be used at elevated temperatures?
Yes. The grease maintains viscosity and sealing performance across a wide temperature range from cold storage to heated equipment operations.
Is this product compatible with standard glass stopcocks?
Yes. Corning high vacuum grease is formulated specifically for glass stopcocks and vacuum connections found in standard lab equipment.
How often should vacuum grease be replaced on stopcocks?
Replacement frequency depends on usage, but annual inspection and reapplication is typical for maintaining optimal seal performance.
