Flexible water connector (flexible connector) — a non-rigid tube or hose with end connections used for connecting a water supply to a fixture, fitting, or appliance. Push-fit fitting — a mechanical fitting that joins pipes or tubes and achieves a seal by pushing the mating pipe or tube into the fitting by hand. The fitting can be removable or non-removable.
4.1.1 Flexible connectors used for delivery of drinking water shall comply with the applicable requirements of NSF/ANSI 61 . 4.1.2 Solder and fluxes shall not exceed 0.2% lead content by mass. Metal alloys shall not exceed 3.7% lead content by mass. 4.1.3 Copper alloy components shall contain at least 56% copper. 4.1.4 Stainless steel components in contact with water shall be made from 300 or 400 series stainless steel. Ferrous steel parts not in contact with water shall be protected by a coating that complies with Clause 4.2. 4.2 Coatings Coatings shall be tested in accordance with and meet the requirements of Clause 5.2 of ASME A1 1 2.1 8.1 /CAN/CSA-B1 25.1 . 4.3 Connections 4.3.1 General Connections shall comply with the performance requirements of this Standard (see Clause 5) and, as applicable, Clauses 4.3.2 to 4.3.7. 4.3.2 Pipe threads NPT or NPTF tapered pipe threads shall comply with the L1 gauge requirements of ASME B1 .20.1 or ASME B1 .20.3 using a tolerance of ± 1 turn. Other pipe threads shall comply with ASME B1 .20.1 . 4.3.3 Hose end threads Hose end threads shall (a) be compatible with hose end threads that comply with ASME B1 .20.7; and (b) comply with the requirements of this Standard. 4.3.4 Fill valve threads Fill valve threads shall comply with ASME A1 1 2.1 9.5, except that fill valve nut threads may be Class 2B. 4.3.5 Solder connections The length and diameter of the joint section of a solder joint end for connection to copper tube or copper tube fittings shall be as specified in ASME B1 6.1 8 or ASME B1 6.22. Flexible connectors for soldering to the water distribution system shall not contain soldered assemblies. 4.3.6 Flare connections Flare connections shall (a) be compatible with flare connections that comply with ASME B1 6.26; and (b) comply with the requirements of this Standard.
4.3.8 Push-fit fittings Connections achieved by push-fit fittings shall comply with ASSE 1 061 and the applicable requirements of this Standard. 4.3.9 Alternate connections Alternate connections shall meet the performance requirements of this Standard. 4.4 Water heater flexible connectors Metallic water heater flexible connectors shall be made of (a) 300 series stainless steel with a minimum wall thickness of 0.25 mm (0.01 0 in); or (b) copper with a minimum wall thickness of 0.7 mm (0.026 in). 4.5 Working pressure Flexible connectors shall function at (a) supply pressures between 1 40 and 860 kPa (20 and 1 25 psi); and (b) intermittent impulse pressures not exceeding 1 240 kPa (1 80 psi). 4.6 Working temperature Flexible connectors shall (a) function at supply temperatures between 4 and 71 °C (40 and 1 60°F); and (b) withstand water at 82 °C (1 80°F) for 0.5 h without failure of the pressure envelope. 5 Performance requirements and test methods 5.1 General 5.1.1 A specimen representing each combination of nominal diameter, connection type, and material shall be tested. 5.1.2 Separate specimens shall be used for each test specified in this Standard.
