Abstract: A pipe coupling apparatus includes a flexible tubular body portion having a body portion a plurality of annular flanges projecting radially outward from the body portion and defining a plurality of annular recesses around the body portion. The body portion can be radially compressed at each end to different degrees, thereby allowing pipes with different diameters to be coupled. The body portion includes a plurality of rods disposed within the material of the body portion. When the ends of the body portion are compressed at different amounts, an intermediate portion of the body portion is tapered, and the rods bend. Clamp bands may be retained within the recesses and may provide the clamping force to radially compress the ends of the body portion to the desired amount.

Abstract: A urinal seal and a method of installing a urinal with a urinal seal located between the siphon outlet on a urinal and the plumbing drain lines of a building structure. The urinal seal generally includes a pipe insert portion and seal portion radially extending outwardly therefrom. The seal portion includes a first surface having an applied adhesive and a second opposing surface having a circumferential flange extending therefrom.

Abstract: A water closet assembly and/or closet flange seal wherein the closet flange seal includes a horn section, a body section, and a sealing fin each formed of a material having a Shore A hardness of less than about 83. The horn section includes a connecting flange, a conical wall, and a ring end wall with the conical wall being integral with and interconnecting the connecting flange and ring end wall. The body section is integral with the horn section and includes a tubular body with an outer face, a first end integral with the horn section, and a second end. The sealing fin extends outwardly from the outer body face, circumscribes the body, and is oriented in a predetermined angle relative to the outer face.
