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.
