High Temperature Resistant Alumina Zirconia Ceramic Washer / Ceramic Sleeve Bushing

If a special shaped or size ceramic washers is required, please advise and we will be happy to quote in both small quantities and large quantities.

High-quality ceramic washer / spacer  (aluminum oxide Al2O3 99.9%, 99.7% and 96% and zirconia ZrO2)

Mingrui manufactures high qualityCeramic Washer / Spacer, made out of High Purity Alumina (96%, 99,7% or 99,9%) and TZP Zirconia ceramics for high and low pressure injection and selection valves. Rotors and Stators are subject to intensive mechanical stress and chemical aggression while having to maintain a perfectly leak free adjustment between the two components. No leak, limited stiction and low wear are the most important parameters to guarantee long life and reliability to your valve. These can be achieved by an adequate surface finish, a perfect flatness of the surfaces in contact and a proper selection of the material. Every application is different and Ceramaret will help you define the parameters required for your particular valve. Ceramic Washer / Spacer are used in valves for many high-tech applications, such as HPLC, micro-HPLC, Medical, Industrial, etc.
