A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
Frequently Asked Questions
Which materials resist Lubricating Oil at high concentrations?
The materials with an A rating (resistant) for Lubricating Oil at 20 °C are: PTFE, HDPE, PVDF, PVC Rigid, Viton (FPM), NBR, SS 316, SS 304. These can generally be used in direct contact.
Which materials should be avoided with Lubricating Oil?
Materials rated D (not resistant) for Lubricating Oil are: EPDM. These should not be used in contact with Lubricating Oil.
Does temperature affect chemical resistance to Lubricating Oil?
Yes. 3 of 11 tested materials show a worse rating at 50 °C than at 20 °C for Lubricating Oil. Materials affected include: HDPE, LDPE, PVC Flexible.
Is PTFE safe for Lubricating Oil?
PTFE is rated A for Lubricating Oil at 20 °C. A rating of A means resistant, B means limited resistance, C means partly resistant, and D means not resistant.
About this data
The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.
A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
