A Bell Reducer Coupler also referred to as a Threaded Reducing Coupler, is a special coupling that features female NPT threads of different sizes on either end. They are used to extend a run of pipe by joining two sections with different diameters.
There are many types of threaded fittings connecting, like NPT, NPS, BSPF, ACME, etc.
NPT: American National Standard Taper Pipe Thread;
NPS: American National Standard Straight Pipe Thread;
BSPF: British Standard Pipe Fitting;
ACME: Acme thread has a flat apex and valley, and a wider tooth shape than an NPT thread.
NPT is areliable choice. The surface of the thread is cone-shaped, and the diameter of the top of the thread is smaller than the diameter of the bottom. This design makes the thread connection with good sealing performance, suitable for high-pressure and high-temperature environments.
With the NPT thread, it provides a secure and leak-free connection for the piping system. Ideal for use in various applications, including industrial, commercial, and residential settings. In both commercial and industrial settings, the Stainless Steel Threaded Reducer stands out for robust performance, enhancing the efficiency and longevity of piping systems.
