Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement fluid, manufactured to meet or exceed original equipment (OE) standards such as IEC 60296 for high-voltage insulation.

How do I know if it is compatible?

Check your equipment manual for “Uninhibited Transformer Oil” or “IEC 60296” requirements. It is a direct equivalent to Shell Diala B.

What does “Uninhibited” mean for this oil?

Uninhibited oil contains no antioxidant additives. It relies on the high quality of the base mineral oil and refining process to maintain stability, as required by certain transformer specifications.
