Abstract: A mechanical coupling for joining pipe elements has a seal. The seal has sealing surfaces with one or more projections that form closable leak paths between the coupling and pipe elements being joined. The leak paths close when the coupling is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings can be discovered during pressure testing and before service pressure is applied.

Abstract: A tube coupling to receive and hold a tube includes a coupling body (10) having a throughway to receive a portion of a tube. A collet (17) in the coupling body has legs (21) with outer surfaces that engage with a tapered surface (24) in the coupling body which urges the legs inwardly to resist withdrawal of the tube. A biasing member (26) provides a biasing force without the tube inserted to urge the legs axially onto the tapered surface. The collet (17) can grip a large variety of pipe diameters. The coupling may be supplied with a number of inserts (30A-D) for sealing with the inner diameter of a pipe, the inserts having different diameters. A tool (50) for preparing the end of a pipe to receive the coupling is also contemplated.

Abstract: A pipe fitting for plain end pipe is formed of housing portions defining receptacles for receiving pipe elements. The receptacles are coaxial with respective axes oriented angularly with respect to each other. Each receptacle has a channel that faces a respective axis with floors at different radii of curvature. Retainers are received within the channels. The retainers have teeth and one or more offset tabs that cooperate with the channels to prevent improper assembly of the fitting. Ring seals are received within channels positioned adjacent to the receptacles. The ring seals cooperate with the retainers to hold the segments in spaced relation sufficient to insert pipe elements into the receptacles when the fitting is pre-assembled. Apertures are provided in the receptacles to permit visual determination of the presence of the retainers post assembly.

Abstract: A pipe fitting having a main body portion into which a retainer is inserted and which, when inserted over a pipe, a flange provided to the pipe contacts first taper portions formed to a front side of the retainer, pushes out the first taper portions, and passes by the retainer. When the main body portion is pulled off the pipe, the flange contacts second taper portions formed to a rear side of the retainer, pushes out the second taper portions and passes by the retainer.

Abstract: Embodiments of a retaining ring for a pipe joint assembly comprise a unitary, ring-shaped body having radially inner and outer surfaces and axially inner and outer surfaces, wherein the radially inner surface is provided with a gripping segment comprising one or more fins, with each of the fins extending radially inwardly. Embodiments further include a wing formed therewith, extending radially outwardly from the radial outer surface to the radially outermost surface. In various embodiments, the retaining ring can be split.

Abstract: The connector comprises a housing having a connection hole where a pipe with a flange is inserted, a retainer having a latching portion that retains the pipe by being arranged at a location facing the connection hole and engaged with the flange, and a checker that is supported by the housing at the retaining position and is movable from the retaining position to the connection confirmation position when the pipe is inserted into the connection hole up to the normal connection position. The checker is configured to release the engagement between the latching portion and the flange, when at the connection confirmation position, by having the retainer that is engaged with the flange of the pipe at the normal connection position pushed to expand the distance of the retainer so that the pipe can be pulled out from the connection hole.

Abstract: A retainer is equipped with a regulation segment, which regulates the position of an O-ring placed in an insertion hole, and a prevention segment, which engages with a spool of a pipe and prevents the pipe from being removed from the insertion hole. Moreover, by moving the retainer toward the minus side in the Y direction and attaching it to an attachment segment, the retainer becomes sandwiched between an opposing wall portion and a tube segment in the X direction. Because of this, the number of parts can be reduced and the retainer that regulates the position of the O-ring can be prevented from being moved in the X direction by the pressure of fluid flowing inside the pipe connector in the X direction.
