Quick-Spot Vacuum and Pressure Gas Leak Detectors

The aerosol can dispenses a foam that bubbles over pressure leaks and forms a crater over vacuum leaks, providing quick and reliable leak detection, while saving time and energy costs. This noncorrosive, nonflammable detector finds leaks in pipes, tubes, fittings, tanks, and cylinders. It washes off with water.

Ultrasonic Gas Leak Detectors
This detector converts ultrasonic waves to an audible sound so you can find leaks. Unlike typical leak detectors, this unit doesn’t rely only on the presence of a gas to work, making it suitable for a wider range of applications. In addition to gas leaks, it identifies ultrasonic sound caused by failing solenoids, valves, and bearings.
For systems under 10 psi, use the optional ultrasonic sound generator.
Refrigerant Leak Detectors for Hard-to-Reach Areas
Detect halogenated refrigerants such as HFCs, CFCs, and HCFCs. Access hard-to-reach areas with the flexible probe. This unit can detect leaks as small as 0.1 oz. per year in air conditioning and refrigeration systems. An audible signal increases in intensity as you approach the leak.

Leak-Detecting Pipe Flange Covers with pH Patch

When a tiny amount of liquid makes contact with the pH patch, it changes color to indicate a leak. Patch is orange when neutral. The wrap-around design of these covers contains acid and caustic pipe leaks, protecting personnel and equipment.
PTFE-coated fiberglass covers are highly resistant to acids, alkalies, and most chemicals except hydrofluoric acid.

Leak-Detecting Dye for Hydraulic Systems
Easy-to-see colors enable you to visually inspect for leaks without ultraviolet light.
Use 1 oz. of dye for every 50 gallons of oil, solvent, wax, or other industrial fluid you're inspecting.
Fluorescent red dye can be enhanced with a UV flashlight.
Leak-Detecting Dye for Water Systems






Easy-to-see colors enable you to visually inspect for leaks without ultraviolet light.
One gallon of water occupies 0.1337 cubic ft. Calculate the number of gallons a tank holds by dividing the tank volume by 0.1337.
Fluorescent dye can be enhanced with a UV flashlight.
Tablets are easy to use for small volumes of water, such as toilets and septic systems. They dissolve in five minutes. Tablets that come in a packet include instructions for detecting a toilet leak.
Liquid is a good choice for larger volumes of water, such as sewers. It disperses faster than tablets and powder.
Powder is the best choice for the largest volumes of water, such as ponds, piping systems in power plants, and cooling towers.
