A superb combination of corrosion resistance, temperature stability
and non-conductivity
Ceramic Sleeve Washer / Ceramic Sleeve Bushing are one of the most thermally resistant washers available. Due to
their outstanding thermal resiustance, alumina ceramic washers are
geared for the most demanding high temperature applications.
Alumina ceramic washers also have outstanding corrosion resistance
and are highly chemically resistant to acids, solvents, and salts.
Additionally, alumina ceramic washers find many uses in high
voltage applications due to their non-conductive electrical
properties.
Alumina ceramic washers are available in both metric and standard
sizes. Please contact us if you have any questions about the
properties or availability of our ceramic washers.
washers made from customer specified ceramic grades or custom
dimensions are available upon request.

Advantages ofCeramic Sleeve Washer / Ceramic Sleeve Bushing:
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact
resistance and delivers 10 times longer working life than metal
plunger. They give a longer life to the sealed packing material.
