The BullThread™ is the first and only female pipe fitting that is soldered into copper water tube without increasing the OD of the tube. The unique design of the BullThread™ follows the tried and true plumbing method. Simply stated “The best method of joining metal pipe to fittings is with threads”. The BullThread™ complies with both the Uniform Plumbing Code and the International Plumbing Code (IAPMO listed file listed 4522). The BullThread™ also complies with NSF61. The BullThread™ is a positive threaded joint between copper water tube and any other fitting. The BullThread is not a union, and it can be installed in non-exposed locations. A BullThread™ copper stubout eliminates the “hidden problems” associated with bullet nose . Our threaded poly plugs allow the plumber to inspect the water line for potential problems.
