Hand-Tite® History
The original patent was Wilmont Tompion’s of 1863 to plug the end of musket barrels during the Civil War. In the 1960s the same design was adapted to make a plug for ceramic sewer pipes which is inconsistent in diameter and roundness. The Hand-tite® plug has a very flexible expansion range to compensate for the irregular inside diameter of the ceramic pipe.
