How to choose Filler
The important part is the sealing element (also called filler) made up of V-formed SS strip and non- metallic filling tape, the material can be changed according to different chemical compatibility requirements.
Graphite filling strip is good to be used in high temperature environment,
PTFE filling strip is for acids and other corrosive mediums
Non-asbestos’ use is increased when the health problems with asbestos became known. But it’s only recommended for low temperature less severe applications due to the rubber content.
Ceramic is in extremely high temperature applications. The filler is not so common as it cannot achieve the same leak tightness as graphite
Marking on outer ring:
- Nominal Size - Pressure Range
- Winding material + Filler Material
- Manufactured to (standard)
