A connector for fluids has a pipe through which the fluid flows. The pipe has a diameter, an inlet end, an outlet end, an expanded area relative to the diameter. The connector also has an excess flow cartridge disposed in the pipe, the excess flow cartridge having a housing for receipt within the diameter, the excess flow cartridge minimizing flow in the pipe if flow exceeds a desired limit, and the excess flow cartridge having a radial opening in a side thereof in register with the expanded area such that flow through the opening flows through the cartridge.

1. A connector for fluids, said connector comprising: a pipe through which said fluid flows, said pipe havinga diameter,an inlet end,an outlet end,an expanded area relative to said diameter, andan excess flow cartridge disposed in said pipe, said excess flow cartridge having a housing for receipt within said diameter, said excess flow cartridge defining a first flow condition to maximize flow from said inlet end to said outlet end and a second flow condition to minimize flow in said pipe if flow exceeds a desired limit, said excess flow cartridge having a radial opening in a side thereof in register with said expanded area such that flow through said opening flows through said cartridge when in said first flow condition, and wherein when flow falls below said desired limit said excess flow cartridge returns to said first flow condition. 2. The connector of claim 1 wherein said expanded area has a tapered portion for directing flow from said expanded area to said radial opening. 3. The connector of claim 2 wherein said tapered portion tapers from said expanded area to a flat area in register with said cartridge within said pipe. 4. The connector of claim 1 wherein said pipe is corrugated. 5. The connector of claim 4 wherein said pipe is not corrugated where said excess flow cartridge is disposed within said pipe in an interference fit such that fluid does not escape around said cartridge. 6. The connector of claim 1 wherein said pipe has an internal shoulder for anchoring said excess flow cartridge therein. 7. The connector of claim 1 wherein said expanded area is adjacent to an inlet portion of said pipe. 8. The connector of claim 1 wherein said expanded area is not corrugated. 9. The connector of claim 1 wherein said housing is received within said pipe in an interference fit. 10. The connector of claim 9 wherein said excess flow cartridge includes a magnet holder attached to an upstream end of said housing, a magnet associated with said magnet holder, and a valve plate mounted within said housing for movement relative to said magnet. 11. The connector of claim 10 wherein said magnet holder includes at least one pin that elastically attaches said valve plate to said magnet holder. 12. The connector of claim 11 wherein said magnet is spaced upstream from said valve plate by legs. 13. The connector of claim 1 wherein said excess flow cartridge includes a valve plate that moves in a downstream direction away from said radial opening when in said second flow condition. 14. A method for controlling fluid flow through a connector for fluids, said method comprising: providing a pipe through which said fluid flows, said pipe having a diameter, an inlet end, an outlet end, an expanded area relative to said diameter;disposing an excess flow cartridge in said pipe, said excess flow cartridge having a housing for receipt within said diameter, said excess flow cartridge defining a first flow condition to maximize flow from said inlet end to said outlet end and a second flow condition to minimize flow in said pipe if flow exceeds a desired limit; and,directing fluid flow directly from said expanded area through a radial opening in a side of said excess flow cartridge in register with said expanded area such that flow through said opening flows through said cartridge when in said first flow condition, and wherein when flow falls below said desired limit said excess flow cartridge returns to said first flow condition. 15. The method of claim 14 further comprising deflecting said flow into said radial opening by a tapered portion that is integral with said expanded area. 16. The method of claim 14 wherein said disposing step includes inserting said cartridge in an interference fit with said pipe such that fluid does not escape around said cartridge. 17. The method of claim 14 further comprising placing said expanded area adjacent to an inlet portion of said pipe. 18. The method of claim 14 further comprising the steps of: installing the housing in the pipe in an interference fit. 19. The method of claim 18 further comprising the steps of: providing the excess flow cartridge with a magnet holder attached to an upstream end of the housing, a magnet associated with the magnet holder, and a valve plate mounted within the housing for movement relative to the magnet. 20. The method of claim 14 further comprising the steps of: providing the excess flow cartridge with a valve plate that moves in a downstream direction away from the radial opening when in the second flow condition. 21. A method for advertising a connector for fluids, said method comprising: providing a pipe through which said fluid flows, said pipe having a diameter, an inlet end, an outlet end, an expanded area relative to said diameter;disposing a given excess flow cartridge in said pipe at a manufacturing facility, said excess flow cartridge having a housing for receipt within said diameter, said excess flow cartridge defining a first flow condition to maximize flow from said inlet end to said outlet end and a second flow condition to minimize flow in said pipe if flow exceeds a desired limit, and wherein when flow falls below said desired limit said excess flow cartridge returns to said first flow condition; andadvertising away from said facility a use for said pipe having said diameter and said given excess flow cartridge and installing the housing in the pipe in an interference fit. 22. The method of claim 21 further comprising the steps of: placing a coupling housing over said pipe; andflaring an end of said pipe for holding said coupling housing on said pipe. 23. The method of claim 21 further comprising the steps of: providing the excess flow cartridge with a magnet holder attached to an upstream end of the housing, a magnet associated with the magnet holder, and a valve plate mounted within the housing for movement relative to the magnet.
