A pipe coupling has first and second segments attached end to end surrounding a central space. The segments define first and second receptacles which receive pipe elements. A port is positioned in one of the segments. The port provides access to the central space. A nipple on the segment extends from the central space and defines a bore aligned with the port. A collar on the segment extends toward the central space. The collar has an outer surface which forms a recess with an inner surface of the segment. A seal is positioned within a channel defined by arcuate keys which surround the receptacles. The seal has a body which defines a first aperture aligned with the receptacles and a second aperture aligned with the bore of the nipple.

A snap fitting for use in plumbing is provided. The snap fitting includes a main body formed of plastic and shaped to extend partially around a cylindrical pipe to snap over the pipe and an inset for extending from an interior side of the main body into a hole in the cylindrical pipe.

A connector for fluidly connecting a collector pipe and a feeder pipe is disclosed, with a retaining member defining a curved base defining a pair of platforms at opposite ends thereof and facing towards each other upon the connector being mounted on the collector pipe. The base is resiliently deformable such that in a non-deformed state, a radius of curvature of the base is smaller than an outer radius of the collector pipe and a distance between the platforms is smaller than a diameter of the collector pipe. The platforms is displaceable away from each other to vary the distance between them to mount the connector and to exert a clamping force on the collector pipe. The connector has a connecting member engaging the feeder pipe. A piping network is also disclosed.

Disclosed is a fluid diverting device which comprises a saddle unit, a water dividing unit and a leakproof tube unit. The saddle unit includes a saddle body, a water inlet through hole and a main pipe accommodating portion. The water dividing unit includes a water dividing main portion, an inlet tube portion and an outlet tube portion. The inlet tube portion is inserted into the water inlet through hole. A screw thread is provided on an external tube wall of the inlet tube portion or on an internal tube wall of the inlet tube portion. The leakproof tube unit includes a sleeve portion, a connecting portion and a leakproof pad. The connecting portion is provided on one end of the sleeve portion and the leakproof pad is in tight contact with the connecting portion. A corresponding screw thread is provided on an external tube wall of the sleeve portion or on an internal tube wall of the sleeve portion. The sleeve portion is screwed with the inlet tube portion in a manner that the external tube wall of the sleeve portion is screwed with the internal tube wall of the inlet tube portion or the internal tube wall of the sleeve portion is screwed with the external tube wall of the inlet tube portion.

The invention discloses a quick tee joint component and a drilling jig component specially for drilling. For installation of a quick tee joint, a drilling jig for quick tee joint is firstly installed on a pipe where a branch pipe is to be added. A bushing of the drilling jig is in threaded connection with the drilling jig, to achieve convenient replacement, and is made of a high-hardness metal material. Under the limiting action of the bushing, the position of a reamer is ensured not to deviate during the reaming process, thereby ensuring the reaming quality. The requirement for different sizes of holes drilled by the drilling jig can be met by simply changing the size of the bushing of the drilling jig. Once reaming is done, fastening bolts are unscrewed so as to remove the drilling jig and a quick tee joint body is installed. A lengthening part of the quick tee joint body guarantees the installation position accuracy of the quick tee joint. In case of vertical installation of the quick tee joint, a notch in the lengthening part allows accumulated liquid to flow out to prevent the fluid from accumulating at the lowest point of the pipe for long time and affecting the working efficiency, thereby avoiding corrosion and extending the service life of the pipe.

A fitting for connecting a branch conduit to a liner installed in a main pipe is configured to mechanically connect to the branch conduit as it is inserted into the branch conduit from inside the main pipe. The mechanical connection is established without rotating the fitting. The fitting can include a body having an outer shaft section for being received in the branch conduit and an inner flange section for opposing the liner within the main pipe. The fastener include one or more teeth that extend radially from the exterior of the shaft section. The teeth can be secured to the shaft section by deforming portions of the fitting body against the teeth. The flange section supports a gasket for sealing against the liner when the fitting is installed. The flange section can include a rim that maintains the gasket in the proper position.

The connection assembly (100) which includes a flange (140) has two internal orifices (150) crossing through and centered on orifice axes (A150) parallel to each other, a front surface (142) and a rear surface (144) parallel to a transverse plane (P140) transverse to the orifice axes (A150), two fluidic coupling elements (170), that have a male body (172) received in a corresponding internal orifice, and a cover (120), configured for being attached to a support (110) in a mounted configuration of the connection assembly. The flange can move with respect to the cover according to a movement supported by the transverse plane, whereas for each male body, a second gasket (188) is interposed radially between the male body and an internal radial surface (S162) of the corresponding internal orifice, each male body being mounted in the corresponding internal orifice and can be tilted with respect to the corresponding orifice axis.
