This floor flange is a class 125 brass pipe fitting with female National Pipe Taper (NPT) threads for securing pipe to floors or walls. It has NPT threads for creating a tighter seal than straight threads and bolt holes for connecting to flat surfaces. This flange is made of brass, which has greater corrosion resistance than steel, and the material’s relative softness allows for easy installation. This class 125 fitting meets standards American National Standards Institute (ANSI) B 1.20.1 and ANSI B 16.15 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
