Abstract
A fitting assembly for establishing a fluid-tight connection with a pipe, the pipe having an aperture in a sidewall thereof, an inner surface, and an outer surface. The assembly comprises at least one adapting member, an internal sealing member disposed about the adapting member adjacent a distal end thereof, compression member disposed about the adapting member adjacent a proximal end thereof, and an external sealing member disposed about the adapting member between the internal sealing member and compression member. The distal end of the adapting member comprises teeth with outwardly extending flanged ends for insertion in the pipe aperture. Operation of the compression member causes the components to exert a compressive force on the sidewall of the pipe, forming the seal.
Claims15
A fitting assembly for establishing a fluid-tight connection with a pipe, the pipe having an aperture in a sidewall thereof, an inner surface, and an outer surface, said fitting assembly comprising:
- at least one adapting member,
- at least one internal sealing member disposed about said adapting member adjacent a distal end thereof,
- at least one compression member disposed about said adapting member adjacent a proximal end thereof,
- at least one external sealing member disposed about said adapting member between said internal sealing member and said compression member,
- said distal end of said adapting member comprising at least one tooth, said tooth having an outwardly extending flanged end,
- a circumference of a portion of said at least one adapting member situate between said at least one internal sealing member and said at least one external sealing member being smaller than a circumference of a wall of said aperture, thus configured for non-engagement of said portion with said wall during and after said fluid-tight connection, and
- wherein said internal sealing member, said compression member, and said external sealing member are movable longitudinally along said adapting member.
A fitting assembly for establishing a fluid-tight connection with a pipe, the pipe having an aperture in a sidewall thereof, an inner surface, and an outer surface, said fitting assembly comprising:
- at least one adapting member,
- at least one internal sealing member disposed about said adapting member adjacent a distal end thereof,
- at least one compression member disposed about said adapting member adjacent a proximal end thereof,
- a first external sealing member disposed about said adapting member between said internal sealing member and said compression member,
- a second external sealing member disposed about said adapting member between said compressing member and said first external sealing member,
- said distal end of said adapting member comprises a plurality of teeth, each having a radially extending flanged end,
- a circumference of a portion of said at least one adapting member situate between said at least one internal sealing member and said first external sealing member being smaller than a circumference of a wall of said aperture, thus configured for non-engagement of said portion with said wall during and after said fluid-tight connection, and
- wherein said internal sealing member, said compression members, and said external sealing member are movable longitudinally along said adapting member.
