LSG 150
The USA-made LSG 150 is ideal for small leaks with diameters ranging from 2” to 5”. and made of aluminum and stainless steel.
Comes with balloon, grounding wire, CO₂ canister, and storage system.
LSG 400
The USA-made LSG 400 is designed for leaks with diameters ranging from 5” to 14”. and made from the same materials as the LSG 150.
Comes with balloon, grounding wire, CO₂ canister, and storage system.
The LSG Stops Leaks of All Sizes
Because all leaks are not created equal, the Leak Stop Gun is available in two models. The LSG 400 is made for stopping leaks from large-diameter tanks and pipes, and the LSG 150 is designed to handle smaller leaks. The two models are made from the same materials, and their differences are highlighted in this table. You’ll also find useful information in the FAQs.

FAQ
1. Why use the LSG 400 instead of the LSG 150?
The LSG 400 is used to seal leaks with diameters ranging from 5 in. to 14 in. (120mm-350mm). In contrast, the LSG 150 is used to seal leaks with diameters ranging from 2 in. to 5 in. (50mm-120mm).
2. What are some common applications for the LSG 400?
The LSG 400 is ideal for use by fire departments, on ships, at petrochemical plants and oil refineries and storage tank facilities, tank truck operators, and in agricultural and biogas environments.
3. What are some common applications for the LSG 150?
The LSG 150 is designed for use with relatively small-diameter pipe leaks such as those caused by excavators used on construction and maintenance projects.

Our Commitment
Our deep concern about the safety and well-being of people, as well as our belief that everyone must do his or her part to protect our planet’s scarce natural resources by engaging in sustainable practices, starts with the development of the LSG. This tool is the result of our collective knowledge of engineering, manufacturing, and workplace health and safety to help commercial and government organizations operate safely.
The LSG reflects the latest in metallurgy, manufacturing, materials science, and design technologies. As technologies in those realms and others advance, we continue to refine the LSG in our pursuit of helping the world become a safer place.
