From the Manufacturer Sewer pipe companies do not manufacture their pipe to common dimensional standards. Instead, pipe is produced to the designs and dimensions best suited for each particular sewer system. Because of this, variations in dimensions of pipe bells, hubs and bores are simply too great to permit making a single universal connector. Fernco Donuts are flexible PVC donut-shaped rings for the compression sealing of sewer pipe joints and DWV connections such as sockets, hubs, bells and spigots. They offer all of the properties necessary to create a strong, lasting joint. Fernco Donuts are available in hundreds of sizes and configurations for use with most brands and types of piping material.
