Gas handling systems and components, including valves, tanks and regulators require leak tightness in order to function properly and prevent loss of gas to the surrounding environment. Often a portable handheld gas sniffing leak detector or a helium leak detector is used to identify leaks. Additionally, for components such as regulators, the helium vacuum method might be employed in a production line to test for external leaks. The level of leak tightness required may depend on the type of gas being handled, it's cost, toxicity, and other factors. Select from one of the products listed below for more details.
Helium Vacuum (HV): An automated method where the test part or test fixture is evacuated to full vacuum while helium is introduced to the opposite barrier of the part.
Helium Sniffing (HS): A manual method of sniffing a pressurized part to detect helium escaping a leak.
Multi-Gas Sniffing (MS): A manual method of sniffing a pressurized part using a variety of instruments specifically designed for non-helium tracer gases such as refrigerants, hydrogen and SF6.
Custom options and systems are available.
