Abstract
The present invention provides a saddle-less fitting having a stepped outer wall surface. The stepped outer wall surface includes a first and second surface and a step. The step includes a first bowed band surface extending from the first outer wall surface a predetermined distance inward towards the inner wall surface. The fitting further includes an insertion portion which includes the second outer wall surface and a second bowed band surface. The first bowed band surface and the second surface are bonded to a prepared pipe with a bonding agent. A more liberal application of the bonding agent may be employed to cause the other fitting and pipe surfaces to further bond together. Once the bonding agent hardens, or becomes cured, a unitary structure is formed which provides a leak-free tap.
