Detect leaks in fuel systems and storage tanks. Add this fluorescent yellow dye to your system and use a UV flashlight (sold separately) to illuminate leaks. Use 1 fl. oz. of dye for every 10 gallons of fuel.

Use colored dye to reveal cracks and surface flaws in most nonporous material. Flaws become visible under natural light and appear as a bright red color. Commonly used for weld inspecting.

More sensitive than natural light kits, these kits use UV light with colored dye to detect cracks, seams, and pores on machined surfaces.

Remove oil, grease, and other contaminants that could alter results while inspecting for flaws. Originally made to meet aerospace standards, these cleaners dry fast without leaving a residue.

Find faulty seams, welding defects, and other surface-level flaws in ferrous materials. These kits come with everything you need to start inspecting parts. Apply the powder to the surface you want to inspect. Then plug in the yoke and it creates a magnetic field that draws the powder to the imperfection, making it easy to spot. Built for rugged environments, the yoke has a sealed design that stands up to chemicals and other harsh conditions. It’s also half the weight of a standard yoke and fits comfortably in your hand, so there’s less fatigue if you use it for extended periods of time.

Also known as a fillet gauge, this gauge measures concave and convex corner weld dimensions.

Check bevel angles, excess weld metal (capping size), length of a corner-weld leg, throat length, and depth of undercut.

Measure internal misalignment of pipe ID, pipe wall thickness after tack welding, and go/no-go fit-up gap.
