    • Description:
    • A Merchant Pipe Coupling is a short length of pipe with female pipe threads on either side.
    • This Threaded Coupling is a short machined pipe with female NPT threads on either side.
    • Uses:
    • They are used to connect two male pipe threads.
    • A Threaded Pipe Coupling is used to connect two pipes together or two male threaded fittings.
    • They can also be used to change a male NPT thread into a female NPT thread.
    • Advantages:
    • Stainless Steel Machined Full Couplings have a smaller diameter than cast couplings and fit closers to the pipe.
    • This is useful where space is limited and when connecting pipes or fittings in confined spaces where a protruding coupling would not fit.
    • Installation:
    • ● Thread one or both of the female NPT threads onto a male NPT thread.
    • Size Classification:
    • ● A threaded coupling is classified according to the size of the male pipe thread they will connect with.
    • ● For Example: a 3/4" coupling will connect to a 3/4" male NPT thread.
    • Also Known as a:
    • ● Full Coupling.
    • ● Threaded Pipe Coupling.
    • Plumbing Coupler.
    • Alternate Options:
    • An Alternatve are Pipe Unions with a hex nut between the female threads.
    • Another alternative are Bell Reducers which are pipe couplers with reduced threads on one end.

    • Materials:
    • This Pipe Coupler is Manufactured in Stainless Steel 304 & 316.


    More Information:

    Stainless steel threaded pipe couplings are widely used in plumbing and piping systems, providing a reliable way of connecting two pipes or fittings with male threads. These couplings are manufactured out of high-quality stainless steel 304 & 316, making them exceptionally durable, long lasting and corrosion resistance. The Stainless Steel Pipe Coupling has internal threads on either end, which allows for a straight forward installation by simply screwing them onto the corresponding male-threaded pipes or fittings. Their NPT tapered thread ensures a secure and leak-proof connection, making them ideal for a wide variety of applications across many industries such as plumbing, chemical processing, oil and gas, and food processing. Stainless pipe couplings are available in a range of sizes to accommodate different pipe diameters. Often used for joining pipe lengths in a straight line, or connecting fittings, pumps and other equipment with male threads together.
