To meet the varied sealing and piston support requirements of Reciprocating Compressors, CVE Manufactures a wide variety of Piston and Rider Rings up to 42" diameter. These rings are offered in a broad range of materials to suit the specific requirements.

CAST IRON: We manufacture piston rings from graded cast iron which provide good sealing over a wide temperature range in applications where adequate lubrication can be provided. All of our cast iron rings are heat tensioned.

BRONZE: Our Bronze Piston Rings offer great wear resistance and are preferred for high temperature and pressures where lubrication may be marginal. The most commonly used Bronze Grade is 80:10:10 (CU-SN-PB) Chilled Casting. Various other grades are also available for different service conditions.

CARBON FILLED TEFLON: Piston rings manufactured from Carbon filled Teflon offers good compressive and shear strength, hardness and wear resistance. They are particularly effective in non-lubricated services and have got excellent corrosion resistance.

We manufacture Radial- Tangent (R-T), Double Tangent (T-T), Pressure Breaker Rings which operate over a long period of time with little or no leakage and a minimum of friction.

We also offer Oil wiper Rings in a variety of materials including Cast Iron, Bronze, Babitt and Carbon filled teflon. Generous drain slots across the face of the ring facilitate removal of lubricants wiped from the rod.
