Lansas Pipe Plugs

Lansas Multi Size Dome Head Inflatable Pipe Plugs

The Lansas Domehead is the most durable multi-size pipe plug available. The unique design of this plug is covered under two U.S. patents. The first patent relates to the 2-ply of cross biased tire cord reinforcement (more on larger sizes). This design allows for controlled expansion of the plug. As this plug inflates it gets larger in diameter and shorter in length. By changing the shape of the plug the side wall stress is kept to a minimum, and this feature also eliminates the longitudinal tearing (end to end) found in plugs by other manufacturers.

The second patent covers our superior end design. The ends are reinforced with a steel “spider” ring wrapped in fabric. The fabric extends from the spider into the body of the plug. This advanced design transfers the stress of inflation from the steel base plate to the fabric reinforced spider ring.

These designs, along with the highest quality materials create a line of pipe plugs that are as much as 50% lighter and substantially more flexible than our competitors.
