Water Detection Paste is a specialized chemical paste designed to detect the presence of water at the bottom of fuel tanks (diesel, gasoline, kerosene, or jet fuel). When applied to a dipstick or gauge rod and inserted into a storage tank, the paste changes color immediately upon contact with water, providing a clear visual indication of water contamination or water level. This produc equavlant to Gasoila brand.

Purpose:

Since water settles at the bottom of fuel tanks due to density differences, detecting it is critical to avoid fuel contamination, engine damage, or microbial growth. This paste is a fast, reliable, and cost-effective method for detecting even small amounts of water in fuel.

Applications:

• Underground and above-ground fuel storage tanks

• Fuel tanker trucks and rail cars

• Fuel stations and distribution terminals

• Power plants and generator fuel tanks

• Aircraft or marine fuel tanks

Features:

• Fast, visible color change on contact with water

• Does not react with fuel (safe in diesel, gasoline, kerosene)

• Good adhesion to dipsticks, rods, and measuring tapes

• Wide temperature range usage

• Detects even small water layers (<1 mm)

How to Use:

1. Apply a thin, even layer of the paste (10–15 cm) on the bottom of a clean dipstick or tank gauge rod.

2. Insert into the tank until it touches the bottom.

3. Wait 5–10 seconds, then remove.

4. If water is present, the paste will change color clearly at the contact point.

Color Change Example:

• Before contact: Blue or Violet

• After contact with water: Pink or Red
