Brass Reducing Sockets

A brass reducing socket is a brass fitting with two female-threaded ends that joins two male-threaded pipes or parts of different sizes in a straight line.
It is used in water lines where the size changes, between a valve and a pipe of a different size and at device outlets. Sizes and stock vary by model.
Main Applications
- Transitions in water lines where the size changes
- Connecting a valve to a pipe of a different size
- Size reduction at device outlets
- Equipment connections in compressed air lines
- Size changes at combi boiler connections
- Joining pipes of different sizes in renovations
