Abstract
A gasket having a generally cylindrical shape is mounted between a side branch pipe and a; connection receiving inlet when inserting and connecting the side branch pipe 12 to the inner peripheral side of a connection receiving inlet of the pipe joint. At the periphery of the mounting rear end side, the gasket has a folded part 2 that is folded in a generally U shape to the outer peripheral side and that can sandwich the end part of the connection receiving inlet. A reinforcing member 3 also may be provided on the gasket. Thus, the gasket is prevented from being pushed in the inner part of the connection receiving inlet when inserting the side branch pipe.
Claims31
A pipe connecting gasket having a generally cylindrical shape and adapted to be mounted between two pipes when connecting a first pipe to a second pipe, wherein the gasket has a flange part at the periphery of the mounting rear end side that projects towards an outer peripheral side to abut a connection receiving inlet end face of the second pipe, and wherein a reinforcing member is disposed on the flange part.
A pipe connecting gasket having a generally cylindrical shape and adapted to be mounted between two pipes when inserting and connecting one pipe to another pipe, wherein the gasket has a flange part at the periphery of the mounting rear end side, which projects to the outer peripheral side to abut a connection receiving inlet end face of the second pipe, and wherein a folded part projects towards the mounting front end side around the outer periphery of the flange part, and can elastically engage the connection receiving end part of the second pipe.
A pipe connecting gasket having a generally cylindrical shape and adapted to be mounted between two pipes when inserting and connecting a first pipe to a second pipe, comprising a gasket body and a reinforcing member provided to project to the outer peripheral side of the mounting rear end side of the gasket body and to abut the connection receiving inlet end face of the second pipe so as to prevent the insertion of the gasket when inserting the first pipe into the second pipe.
A pipe connecting gasket having a generally cylindrical shape and adapted to be inserted between two pipes when inserting and connecting a first pipe to a second pipe, wherein a gasket body has an integrally formed insertion prevention edge reinforced by a reinforcing member so as to project to the outer peripheral side, and wherein the insertion prevention edge abuts and engages a first stepped part provided at the inner peripheral side of the connection receiving inlet of the second pipe in an insertion direction.
A gasket, comprising:
- a gasket body having an annular shape and a tapered inner peripheral seal;
- a flange portion extending outwardly from the gasket body at approximately a 90 degree angle and being annularly formed around the gasket body;
- a folded portion projecting from the flange portion at approximately a 90 degree angle and the folded portion being annularly formed around the flange portion;
- the gasket body, the flange portion and the folded portion being monolithically molded from a resin material and combining to form a channel to engage a connecting inlet of a pipe;
- and
- a reinforcing member disposed on the flange and folded portions, the reinforcing member comprising a resilient material.
