  • Patent number: 7980602
    Abstract: A pipe fitting facilitates joining of a high-density polyethylene (HDPE) pipe to a polyvinyl chloride (PVC) pipe. The fitting has a HDPE body. A ring-shaped PVC insert is positioned within an inner surface of the body at one opening of the body. An inner surface of the PVC insert is threaded so that a PVC pipe that has a threaded outer surface can be screwed into the PVC insert. A compression ring is installed over the outer surface of a portion of the body that surrounds the PVC insert. Prior to installation, the inner diameter of the compression ring is smaller than the outer diameter of the portion of the body that surrounds the PVC insert. For this reason, when the compression ring is installed, the compression ring compresses the portion of the body that surrounds the PVC insert, holding the PVC insert within the body.

    Abstract: A fluid seal generally comprising a first fitting portion (50) and a second fitting portion (28), wherein at least one of the fitting portions can be deformed or deflected in a sealing relationship relative to the other fitting portion to form the fluid seal. A fitting includes a first fitting portion comprising a small projection (52) extending from a substantially planar surface. The fitting further includes a fitting portion comprising a substantially planar second surface (59). A fluid seal is created by forcing the small projection of the first fitting portion and substantially planar surface of the second fitting portion together. As they are forced together, the projection deforms to form the fluid seal. The fitting can be used to connect tubes, pipes, a valve, a manifold, and combinations thereof. The sealing method can also be used to protect the components of a pressure sensor from the corroding effects of process fluid vapors.

  • Patent number: 7350831
    Abstract: A water pipe includes a pipe main body made of a synthetic resin and an annular metal inner piece inserted into an end of the pipe main body. The inner piece has its diameter increased from the inside of the pipe main body so as to increase the diameter of at least a part of that portion of the pipe main body which corresponds to the inner piece. The inner diameter of the inner piece the diameter of which has been increased is almost the same as that of a portion of the pipe main body which is not enlarged by the inner piece.

  • Patent number: 7347456
    Abstract: An apparatus is provided for joining and sealing conduits, includes edge trim, a sleeve, and a retaining element. The edge trim is shaped to mount upon and engage an end of a conduit. The sleeve extends between the conduits and at least partially surrounds the edge trim. The sleeve may be made of compressible material, such that when the retaining element surrounds a portion of the sleeve and the edge trim, the retaining element generally compresses the portion of the sleeve portion underlying the retaining element and displaces the sleeve material to expand on either side of the retaining element and limit movement of the retaining element. The method of joining and sealing conduits includes mounting the edge trim and a retaining element upon an end of a conduit, extending a sleeve between the conduits, and sliding the retaining element over the sleeve toward the end of the conduit.

  • Patent number: 7316427
    Abstract: A hollow plastic product including a hollow main body, a reinforce member and a connector pipe is provided. Such a hollow plastic product is, for example, used advantageously as a component of an air-intake system or fuel supply system of an automobile. In one example, the hollow main body is a duct, hose or tube extending over a length, and the reinforce member is ring-shaped so that it extends around a circumference of an outer surface of the hollow main body. The reinforce member is manufactured by injection molding and is used as an insert when blow-molding the hollow main body, so that the reinforce member is integrally formed with the main body. The reinforce member has a defined welding surface formed with a first hole, to which one end surface of a connector pipe is thermally welded. Then the hollow main body is formed with a second hole in alignment with the first hole, thereby defining a fluidic communication between the hollow main body and the connector pipe.
