2. Solder ring fitting - Wikipedia

   en.wikipedia.org/wiki/Solder_ring_fitting

   The fittings come in a variety of configurations, such as tee-pieces, straight couplers, elbows or bends, reducers (to join pipes of different diameters), stop-ends, and there are versions with screw threads (male or female) at one end to fit taps and iron pipes. Valves such as stoptaps & gate valves are also available in solder ring configuration.

3. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   Generally, copper tubes are soldered directly into copper or brass fittings, although compression, crimp, or flare fittings are also used. Formerly, concerns with copper supply tubes included the lead used in the solder at joints (50% tin and 50% lead). Some studies have shown significant leaching of the lead into the potable water stream ...

4. Flare fitting - Wikipedia

   en.wikipedia.org/wiki/Flare_fitting

   Flared fittings are an alternative to solder-type joints that are mechanically separable and doesn’t require an open flame. Copper tube used for propane, liquefied petroleum gas, or natural gas may use flared brass fittings of single 45°-flare type, according to NFPA 54/ANSI. Z223.1 National Fuel Gas Code.

5. Compression fitting - Wikipedia

   en.wikipedia.org/wiki/Compression_fitting

   A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect

6. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Fittings for non-threaded conduits are either secured with set screws or with a compression nut that encircles the conduit. Fittings for general purpose use with metal conduits may be made of die-cast zinc, but where stronger fittings are needed, they are made of copper-free aluminum or cast iron. Couplings connect two pieces of conduit together.

7. Twist-on wire connector - Wikipedia

   en.wikipedia.org/wiki/Twist-on_wire_connector

   Twist-on wire connectors are not generally recommended for use with aluminum wire in the United States. [1] The U.S. Consumer Product Safety Commission disapproves wire nuts for aluminum wire; instead, special crimp connectors are called for, and as of 2011 the CPSC asserted qualified, second-preference approval of a certain kind of screw ...

8. Push-to-pull compression fittings - Wikipedia

   John Guest (Established in 1961, West Drayton, UK) developed the Speedfit push-fit connector for compressed air use in 1974, and introduced plumbing fittings in 1987. [2] These fittings are white plastic, and are unscrewable to replace components, like Hep2O, but also have a push-release mechanism. Speedfit uses plastic pipe support inserts.

9. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Copper pipe fittings. Fittings are also used to split or join a number of pipes together, and for other purposes. A broad variety of standardized pipe fittings are available; they are generally broken down into either a tee, an elbow, a branch, a reducer/enlarger, or a wye. Valves control fluid flow and regulate pressure.
