Manufacturer:
The T&S Brass B-3945 Adapter 2-inch NPT Female to 1 1/2-inch NPT Male is a connector that is used to connect pipes or fittings with varying thread sizes by having a 2-inch female NPT inlet and a 1 1/2-inch male NPT outlet. The adapter allows fluid to pass through it because it connects the larger-diameter connection to the smaller-diameter connection. It is fitted between similar threaded NPT components in compatible plumbing systems where there is a need to reduce the size.
