Flanges (FPT)

A schedule 80 PVC FPT flange is used to transition from a male-threaded-end pipe to a flange. The FPT end of the flange fitting is screwed onto the MPT end of the pipe. The flange can then be mated with another flange to connect another pipe or it can be paired with a piece of equipment.

Schedule 80 PVC has thick walls and is designed to contain pressurized liquids below 140⁰ F. Although schedule 80 PVC isn’t suitable for hot water applications, all PVC varieties have a high chemical resistance, and thus are often used in corrosive environments.

The flange itself is a flat, disc-shaped surface that is flush with a central opening into the body of the fitting. The disc has a series of holes around the outer edge, and a shallow groove encircles the central opening. To connect the fitting, an O-ring is placed in the groove, and another flange is fitted to the first in such a way that the O-ring is seated into the groove on both flanges with the holes around the outer edges aligning. Bolts are inserted into these holes and tightly fastened with nuts. As the bolts are tightened, the two flanges are drawn together. This compresses the O-ring and creates a tight seal. 

Flanges are valued because they are removable and the O-ring is replaceable. Large tanks often come with flanged connections, and they are commonly found in industrial settings and in wastewater treatment plants.
