Material comparison at 20 °C
Resistance overview
Nylon (PA) has limited resistance (C) to Lubricating Oil at 20 °C. This indicates that the chemical has a noticeable effect on the material, which may include visible swelling, softening, or a measurable loss of tensile strength. Use is generally limited to short-term or intermittent contact where full structural integrity is not required. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.
Application context
Lubricating Oil is commonly encountered in fuel storage and transfer and power generation. Nylon (PA) (Polyamide (nylon)) is a thermoplastic typically used for tanks, piping, containers and liners. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
Nylon (PA) has limited resistance to Lubricating Oil and should only be used for short-term or intermittent contact at ambient temperature. The C rating means the material undergoes noticeable changes — swelling, loss of strength, or surface degradation — that make it unsuitable for permanent installations. For prolonged or continuous exposure, HDPE, Polycarbonate, PVC Rigid offer significantly better resistance and are rated A.
Did you know?
Polyamide (nylon) is commonly chosen for tanks, piping, containers and liners because of its combination of chemical resistance, mechanical strength, and cost-effectiveness.

About Nylon (PA)
Polyamide (nylon) resists fuels, oils and many solvents. Mineral acids, even dilute, and strong oxidisers attack it, and it absorbs water.

A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
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.
