Urinal seal and method of installation

A urinal seal comprising:

• a pipe insert portion having a frusto-conical shape;
• a seal portion radially extending outward from said pipe insert portion, said pipe insert portion including a wall extending from the seal portion to an end;
• wherein said wall has a thickness that is tapered to a thinner thickness from said portion proximate to said seal portion to said wall proximate to said end;
• a circumferential flange extending from said seal portion and substantially uniformly spaced from said pipe insert portion;
• a sealant applied to the sealing portion and wherein the adhesive is applied to the opposing side of said seal portion from said circumferential flange;
• and
• a circumferential adapter sealing surface located between said pipe insert portion and said circumferential flange.

A urinal seal comprising:

• a pipe insert portion having a frusto-conical shape and wherein said pipe insert portion is approximately equal to or less than two inches at its widest outer diameter;
• a seal portion radially extending circumferentially outwardly form said pipe insert portion and proximate to said widest outer diameter of said pipe insert portion and wherein said seal portion includes a first surface opposed to an adapter sealing surface;
• and
• a sealant adhered to said seal portion and wherein said sealant is adhered to said first surface, and said adapter sealing surface is free of said sealant.

A method of installing a urinal on a vertical wall, the urinal including a siphon outlet and the wall including a drain inlet having an inner drain surface with an inner diameter and a wall adapter having an adapter flange, said method including the steps of:

• providing a urinal seal having a pipe insert portion and a flange extending radially outward from the pipe insert portion and a sealant;
• inserting the urinal seal partially into the drain inlet until the pipe insert portion sealingly engages the inner drain surface;
• mounting the urinal to the vertical wall with the siphon outlet engaging the flange of the urinal seal;
• and
• fastening the urinal to the wall to compress the flange between the siphon outlet and the drain inlet, and the wall adapter to create at least three watertight seals including:
• a first water tight seal between an outer surface of the pipe insert portion and the inner drain surface, creating a second water tight seal between the siphon outlet and the flange of the urinal seal and creating a third water tight seal between the adapter flange and the flange of the urinal seal.

A urinal seal configured to provide a water tight seal between a urinal and at least one of a pipe and a wall adapter plate coupled to said pipe, said urinal seal comprising:

• a pipe insert portion having a frusto-conical shape;
• a seal portion radially extending outwardly from said pipe insert portion to an outer diameter and having a first surface and an opposing second surface;
• a circumferential flange extending from said seal portion on said second surface and configured to directly engage the wall adapter plate;
• a sealant applied to said first surface of said second portion and configured to adhere to the urinal;
• and
• a circumferential adapter sealing surface located between said pipe insert portion and said circumferential flange and wherein said circumferential adapter sealing surface is configured to directly engage at least one of the wall adapter plate and the pipe.
