  2. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    The bodies of fittings for pipe and tubing are often the same base material as the pipe or tubing connected: copper, steel, PVC, CPVC, or ABS. Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the ...

  3. AN thread - Wikipedia

    en.wikipedia.org/wiki/AN_thread

    A 37° flare type end fitting for flexible hose. The AN thread (also A-N) is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army Air Corps and Navy, hence AN.

  4. Copper tubing - Wikipedia

    en.wikipedia.org/wiki/Copper_tubing

    Common sizes are 15 mm and 22 mm. [7] Other sizes include 18 mm, 28 mm, 35 mm, 42 mm, 54 mm, 66.7 mm, 76.1 mm, and 108 mm outside diameters. Tubing in 8 mm and 10 mm outside diameters is called a "micro bore" and is easier to install, although there is a slightly increased risk of blockage from scale or debris.

  5. Nominal Pipe Size - Wikipedia

    en.wikipedia.org/wiki/Nominal_Pipe_Size

    Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

  7. 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

  8. National pipe thread - Wikipedia

    en.wikipedia.org/wiki/National_pipe_thread

    Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal Pipe Size diameter, and considerably so for small sizes. Pipe of a given size in a different Schedule than Schedule 40 provides a different wall thickness while maintaining the same outside diameter and thread profile as ...

  9. JIC fitting - Wikipedia

    en.wikipedia.org/wiki/JIC_fitting

    JIC fitting systems have three components that make a tubing assembly: fitting, flare nut, and sleeve. As with other flared connection systems, the seal is achieved through metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing.
