• Description:
• ● A bell reducer is a threaded reducing coupling that features female threads of different size on either end.
• ● It is a bell shaped fitting with a smaller diameter opening on one end, and a larger diameter opening on the other.
• Uses:
• ● A Bell Reducer Coupler, also referred to as a Threaded Reducing Coupling, is used to reduce or increase a pipe thread size.
• ● Used to connect two pipes of different diameter sizes.
• Advantages:
• ● These threaded pipe reducers decrease the pipe size from a larger bore to a smaller bore in a smooth uniform manner unlike the sharp change in size of the Reducing Bushing.
• Installation:
• ● Thread the larger female threads onto the same size male threads, to decrease the female thread size.
• ● Thread the smaller female threads onto the same size male threads, to increase the female thread size.
• Size Classification:
• ● These reducing couplings are classified by the larger female thread first and the smaller female thread next.
• ● For Example: a 1" x 3/4" bell reducer will have a 1" internal thread and a 3/4" internal thread.
• Also Known as a:
• ● Bell Fitting.
• ● Bell Coupling.
• ● Pipe Coupling Reducer.
• Alternate Options:
• ● An alternative are Reducer Bushings which are also pipe reducers, however instead of having internal threads on each end, they have male threads x female threads.

• Materials:
• ● Manufactured with 304 & 316 stainless steel.

More Information:

Threaded bell reducer couplings are pipe fittings widely used in plumbing and in piping systems, designed to connect pipes and fittings of different sizes. They are designed with internal threads on each side of a conical reducer providing a secure and tight connection between different sized pipe fittings. One end of the concentric reducing coupling is larger to accommodate the larger diameter pipe, while the other end is smaller to fit the smaller diameter pipe. The concentric bell design facilitates a seamless and smooth transition between the two sizes. The tapered NPT Thread minimizes the risk of leaks and simplifies installation, making these pipe reducers ideal for a range of applications, from residential plumbing projects to industrial applications. These NPT thread reducers are manufactured out of stainless steel 304 and 316, making them corrosion resistant and robust.
