CPI Compression

Packing and Wiper Rings

Packing Rings

Using a wide range of metallic and non-metallic materials and a variety of designs we offer a large selection of packing rings designed for unidirectional and bidirectional sealing, low-pressure vent and gas purge sealing.

Wiper Rings

We design each and every one of our wiper rings to provide a tight seal that works to keep lubricants where they belong – within the crankcase. In doing so, we can help keep your compressor running longer and more efficiently.
