Sealing Materials
For sealing at Room Temperature we offer a number of greases, including specialist high-vacuum greases from Apiezon®.

For cryogenic seals we only ever recommend high purity Indium, which avoids the possible inclusion of filaments of oil and grease that can render recycled Indium wire-stock unusable.
