Compressor Oil RP 268 and RP 460 are specially designed for the lubrication of cylinders and rod packings in natural gas reciprocating compressors having force-feed lubrication systems.

These compressor oils are formulated with an advanced, non-fatty additive package to provide excellent high temperature stability, very good lubricity and wear protection, as well as minimizing deposit formation. They are primarily recommended for use in compressing sour, wet or contaminated natural gas. The higher viscosity RP 460 is especially suited for use in higher pressure applications.

Compressor Oils RP 268 and RP 460 may also be used for the initial break-in (first 500 hours running) of compressor cylinders in sweet or dry gas service.

Typical characteristics are shown below:

Note: In selecting a compressor oil it is important to know not only the equipment manufacturer and model, but also the gas being compressed and the discharge pressure. In the table below, various gases are categorized for the type of lubricant required.

Please note that in the case of chemically active gases such as chlorine, oxygen and hydrogen chloride no petroleum lubricant is recommended.
