Abstract: A drain fitting for use in an irrigation system for draining water from the irrigation system, regardless of pipe size in the irrigation system, generally includes a grip portion and a neck coupled to the grip portion. The neck defines a first engagement portion having a first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the first diameter of the first engagement portion, and a second engagement portion having a second diameter, different from the first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the second diameter of the second engagement portion.

Abstract: A pipe-fitting adaptor assembly connectable to the coupling end of a pipe fitting is provided for reconfiguring existing pipe fittings with alternate pipe coupling ends. The fitting adaptor assembly has a tubular receptacle member configured to fit over and seal against an insert member of the fitting. A sliding retention ring carried along a ramped section of the fitting insert member interlocks with an opening formed in the sidewall of the receptacle member of the fitting adaptor assembly, such that decoupling forces tend to expand the locking ring further into the sidewall opening of the fitting adaptor assembly. The fitting adaptor assembly has a coupling end configured differently than the insert member for connection to otherwise incompatible alternative pipe sizes and/or pipe coupling configurations.

Abstract: A fitting connectable to an end portion of a pipe generally includes a tubular insert member configured to be received at least partly within the end portion of the pipe, and a retention member coupled to the insert member and configured to be received at least partly within the end portion of the pipe. The retention member operates in conjunction with the insert member to engage the end portion of the pipe and impart an increased force against an inner wall of the pipe in response to forces tending to separate the fitting from the end portion of the pipe. The insert member includes a plurality of reinforcement ribs formed on its inner surface which provide support to the insert member and help prevent damage thereto from transverse bending forces applied during installation.

Abstract: A fitting connectable to an end portion of a pipe generally includes an insert member configured to be received at least partly within the end portion of the pipe, and a retention member coupled to the insert member and configured to be received at least partly within the end portion of the pipe. The retention member operates in conjunction with the insert member to engage the end portion of the pipe and impart an increased force against an inner wall of the pipe in response to an increase of internal pipe pressure, thereby frictionally securing the end portion of the pipe on the insert member as internal pipe pressure increases during use.

Abstract: A fitting connectable to an end portion of a pipe generally includes a housing configured for receiving at least part of the end portion of the pipe into the housing, and an insert member disposed at least partly within the housing. The insert member is configured to be received at least partly within the end portion of the pipe when at least part of the end portion of the pipe is received into the housing. A retention member is movable relative to the housing for selectively connecting the fitting to the end portion of the pipe. The retention member is movable to press at least part of the end portion of the pipe radially against at least part of the insert member to help secure the fitting to the end portion of the pipe when the end portion of the pipe is received into the housing.

Abstract: An electrical connector and method of making an electrical connection wherein the connector includes a housing having an upper portion and a lower portion rotatable relative to each other, a chamber, a cavity configured to receive a first wire, and a first conductive member positioned within the chamber. The first conductive member is configured to extend into the cavity and establish electrical contact with a conductor of the first wire upon rotation of the upper housing portion relative to the lower housing portion. A second conductive member can be electrically coupled to a conductor of a second wire. The second conductive member is also electrically coupled to the first conductive member such that electrical conductivity can thus be established between the conductor of the first wire and the conductor of the second wire.

Abstract: An electrical connector having a housing with a chamber and at least one wire receiving passageway for receiving two or more wires into the chamber. An engagement member is configured to be rotatable within the chamber. The engagement member is configured to fracture a portion of any insulating covering on each wire and complete electrical contact between the conductors of the two or more wires upon rotation of the engagement member.

Abstract: A saddle tee and tap combination for making a fluid connection with an irrigation line in an irrigation system. The saddle tee includes a base having a passage therethrough, and a clamp thereon for engaging an irrigation line. The clamp holds the irrigation line in alignment with the passage, and compresses the irrigation line into an generally oval cross-section elongated in the direction of the axis of the passageway. The tap has a tip with a pointed end adapted to be inserted into the passageway so that the pointed end penetrates the wall of the irrigation line engaged in the clamp, in the direction of the elongation of the cross section.
