  • Patent number: 10213591
    Abstract: A second part extending around a first part in a plugged-together state. The second part has snap-in element with an inwardly protruding projection for meshing with a complementary recess on an outer surface of the first part to hold the second part fixed in the axial direction on the first part. Both parts have a central passage opening. One part has an end area expanding towards the outlet opening in a connection area, and the other part is connected to an elastic section, arranged in its interior. The front end of the elastic section is pressed into contact with the expanded end area of the opposite part. The projection of the snap-in element maintains the first and second parts meshed together, so that the elastic section exerts a sealing function due to the pressure on the expanding end area.

  • Patent number: 10161551
    Abstract: A quick-connector connecting a first pipe and a second pipe. The quick-connector includes a housing that extends about a first axis and defines a bore that extends axially therethrough. A grab ring is disposed in the bore of the housing and includes a body that extends about and along the first axis between a first end and a second end and defines a passage that extends between the first and second ends for receiving one of the first or second pipes. A plurality of protrusions extend from the body in the passage for clamping against the received pipe to prevent the received pipe from being axially removed from the passage. A plurality of hinges are spaced from one another about the body for allowing the body to uniformly and circumferentially flex about the hinges relative to the first axis when the first or second pipe is received in the passage.

  • Patent number: 10006575
    Abstract: A push-to-connect modular cartridge for a plumbing fitting includes a cylindrical cup having an annular surface at one end and a cylindrical shoulder at an opposite end. A circular seal is positioned against the annular surface, and a circular backing ring is positioned against the seal on a side opposite the annular surface. A grab ring including inwardly projecting tines is seated against the backing ring on a side opposite the seal, and a containment ring contacts the grab ring on a side opposite the backing ring. The containment ring is engaged by the shoulder of the cup to hold the containment ring, grab ring, backing ring, and seal together. This modular push-to-connect cartridge can be welded to a plumbing fitting which uses significantly less material, thereby greatly reducing the cost to manufacture.

  • Patent number: 8491012
    Abstract: A tube coupling including a body having a bore and an open end, a slidably movable jaw ring received in the bore, a bushing fitted into the body open end having a surface facing the movable jaw and defining a stationary jaw, and a resiliently expandable grab ring disposed in the bore between the movable and stationary jaw. With a tube end being inserted into the bore and through the grab ring, and with the tube being grabbed by the grab ring to retain the tube end in the bore, the movable jaw is responsive to fluid pressure received within the tube to slidably move towards the stationary jaw face such that a portion of the grab ring is clamped therebetween.

  • Patent number: 8485560
    Abstract: A welding spacer includes a spacer body having a first pipe-engaging face and a second socket-engaging face. The spacer may be formed from any suitable material, including a liquid-degradable or heat-degradable composition. A spacer thickness separates the first face and the second face. The spacer thickness may comprise solid material or it may have one or more hollow portions. A peripheral edge is provided on the spacer body. One or more deformable members may be provided on the peripheral edge for retaining the spacer in a structure. The welding spacer may be incorporated in a pipe assembly that includes a first pipe segment and a second pipe segment. The first pipe segment has a socket at a first pipe end with an interior shoulder to seat the welding spacer.

  • Patent number: 8430432
    Abstract: A pipe coupling with an anchoring arrangement for locking the pipes together axially. The anchoring arrangement comprises a tubular casing, a frusto-conical gripping ring with inwardly projecting gripping teeth and tensioning bolts for tightening the casing about the frusto-conical gripping ring. The frusto-conical gripping ring is formed of a plurality of arcuate segments which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.
