Home / Applications / Piston/Sleeve Assemblies

These pieces represent a large part of our business we developed by learning how to achieve the very tight diameters, and cylindricities needed for these applications. With piston/sleeve clearances down to .00004″, pumping is possible without use of flexible seals. Applications include cryogenic pumping and precision metering. Materials can be alumina, industrial sapphire, or most other technical ceramics.
