McCabe Gasoline Indicator Paste is a light sky blue paste that turns a darker blue when immersed in:
- Gasoline
- Reformulated Gasoline (RFG)
- Diesel
- Kerosene
- Naphtha
- #2 heating oil
- Light crude oil
- Jet fuel
- Petrochemicals
- Plant oils.
to use:
Spread a smooth, even coat of the product on the bob or gauging device where you expect the air/product interface to be located.
Once entering the product, leave immersed for approximately five to ten seconds and the paste will turn a dark blue. (Please note: some heavier products may require a longer immersion time.)
When reading the results, note a straight, sharp demarcation on the gauging device, light blue above/dark blue below.
