Multi-Size Domehead plugs from Lansas manufactured by Vanderlans and Sons, Inc.

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.

The Lansas Domeheads™ are manufactured and stocked with our standard ozone protected natural rubber outer layer. They are also available with a nitrile or neoprene layer, as well as stainless steel end plates for use in chemical and petroleum applications.

The 050 Series Domehead™ Back Plugs are designed with lifting eye(s) on both end(s) and a 1/4" inflation port. Larger sizes have an additional 1/2" inflation port. The 051 Series Domehead™ Front is equipped like the back plug, however, it also includes a 1/4" + 3/4" test thru port for air testing and pressure monitoring.
