KO-17 hi-temp penetrant is a visible dye penetrant used to find flaws on surfaces at elevated temperatures of up to 350°F (176.7°C).

KO-17 saves time for weldmet inspection allowing the inspection to take place at pre-heated temperatures.

Complies with low sulfur and low halogen requirements.

Because KO-17 works at high temperatures, the heat drives contaminants from flaws and heat-expanded flaws trap more penetrant, giving stronger indications.
