US 9,752,706 B2 · Sealed transverse locking pipe and fittings

Abstract

A pipe and fitting coupling system includes a first pipe, a second pipe, and a joint. A receiving end of the second pipe includes a first flange, a second flange, a groove, and a sealant. The second flange extends further than the first flange. The groove is disposed at the pipe diameter and between the first flange and the second flange. The first flange has an inwardly angled face to meet the groove and the second flange has an outwardly angled face to meet the groove. The sealant is disposed in the groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant.
