Pipe Plugs & Pipeline Testing Equipment

Lee Jensen Sales provides a comprehensive range of inflatable and mechanical pipe plugs designed for blocking, bypass, and air testing applications. Our inventory features high-quality plugs from industry-leading manufacturers, engineered to withstand the rigorous pressures of sewer and water main installations. Whether you are dealing with small residential laterals or massive 96-inch municipal trunk lines, we provide the correct equipment for the job to ensure a secure seal and a safe working environment. Our selection includes single-size and multi-size plugs, as well as specialized bypass plugs that allow flow to continue while repairs or inspections are performed.

Safety is our primary concern when it comes to high-pressure pipe testing, which is why we emphasize selecting the right tool for your specific pipe diameter and back-pressure requirements. We offer these plugs for both sale and rental at our Crystal Lake and Mokena locations, ensuring you have access to the exact sizes you need without maintaining a massive inventory of your own. Every rental plug undergoes a strict inflation and pressure-retention test before it leaves our shop, giving you the confidence that your equipment will perform reliably in the trench. From manhole vacuum testers to joint testers and basic blocking plugs, our team is here to ensure you have the precise gear required for a successful, OSHA-compliant test.
