KF-25 Centering Ring, Aluminum

Centering Rings sit between two KF or "NW" flanges to provide a seal. A clamp is needed to squeeze the flanges together to provide the seal. Aluminum centering rings provide a cost effective option for vacuum systems which do not have corrosive gases or methanol in the vapor stream.  High temperature resistance.

• -50℃~200℃, oxidation & corrosion resistance.
