ASME B16.11 Coupolet Fitting Manufacturers and Suppliers:
Coupolet is a type of pipe fitting used to connect a smaller diameter pipe to a larger diameter pipe or vessel. It is essentially a type of weldolet with a socket-shaped end that allows for a smooth transition between the pipes.

The dimensions of a coupolet can vary depending on the specific application and the sizes of the pipes being connected. However, typically, the socket end of the coupolet will have a smaller diameter than the pipe or vessel it is being connected to, while the other end will have a larger diameter to accommodate the smaller pipe.
Coupolets are commonly used in high-pressure and high-temperature piping systems where a smooth transition is needed to prevent turbulence and stress concentration. They are made from a variety of materials, including carbon steel, stainless steel, and other alloys, and are available in various configurations such as reducing coupolets, straight coupolets, and reinforced coupolets.
We have the ready inventory of Coupolet Fitting in the different size ranges of 1/8 Npt, 1/4 Npt Coupolets.
