O-Ring Care - Agilent Technologies VS Series Operation Manual

O-ring Care

When removing, checking or replacing O-rings, keep in mind the following:
xvii
VS Series Component Leak Detectors
Agilent recommends replacing all O-rings during routine
NOTE
maintenance or during any maintenance procedure requiring
that O-rings be removed.
Due to the effective cleaning nature of VacuSolv solvent and
NOTE
its residue-free properties, Agilent' Component and
Spectrometer Cleaning Kit (Part Number 670029096), used in
accordance with the kit instructions, is recommended for
cleaning spectrometer components. The kit can also be used for
fine cleaning of other parts in the leak detector's vacuum
system such as valves and fittings. No rinsing steps or
high-temperature drying are required following cleaning with
VacuSolv. Although appropriate precautions are advised,
VacuSolv is compatible with most materials and does not
contain toxic chemicals or CFCs (chlorofluorocarbons). Other
acceptable solvents are isopropyl alcohol (IPA) or Dow
Corning
Remove O-rings carefully with your fingers. Do not use metal
CAUTION
tools for this task; this prevents scratching of any sealing
surfaces.
Wipe all O-rings clean with a lint-free cloth before
installation to ensure that no foreign matter is present to
impair the seal.
Do not use grease or any other substance on O-rings that
will come in contact with the spectrometer.
Do not use alcohol, methanol or other solvents on O-rings.
Doing so causes deterioration and reduces their ability to
hold a vacuum.
Agilent does not recommend the use of vacuum grease. If
applicable, apply a small amount of Apiezon
wipe the O-rings shiny dry.
