Hopefully, if you have found this blog, it’s not because you’re in the middle of a crisis involving a vacuum leak on a pump. But should that be the case, look no further. Apiezon Sealing Compound has a putty-like consistency, used to fill gaps and joints on the rotary side of a vacuum system. It is designed to form a seal around flat, unground joints. Keep in mind, this is a temporary fix, depending on the application.
An example of use might be sealing glass cylinders to metal plates. It is used for vacuum work where low vapor pressures are not required.
The sealing compound softens between 40-50 C (104-122 F). Maximum temperature usage is 30 C (86 F). The Vapor pressure is 1x1o-4 Torr at 20 C (86 F).
For movable joints, Apiezon makes a high temperature and ultra-high temperature grease. Designed for lubricating, though the grease is silicone free. Used in vacuum systems such as desiccators, rotary evaporators, vacuum traps, and ground glass joints.
As always, our knowledgeable Staff would be happy to assist you with finding the right fix and to answer any questions that you may have.
