Rubber Reducing Size Donut, 3 X 1-1/2 In.

The Fernco P33U-139 is a flexible PVC donut-shaped ring designed for the compression sealing of sewer pipe joints and DWV (drain, waste, and vent) connections. It fits into sockets, hubs, bells, and spigots to create a watertight seal without requiring special tools or additional sealants. This reducing donut bridges two different pipe sizes—3 inches and 1-1/2 inches—making it essential for transitions in drainage systems.

Whether you're repairing existing plumbing, joining dissimilar pipe sizes, or installing new drainage systems, this flexible ring prevents gaps and leaks by conforming to the pipe dimensions. Its soft PVC composition allows it to be pressed into place without damage, and it resists degradation from chemical runoff, soil acidity, and other corrosive elements commonly encountered in drainage applications.

Features and Benefits

• Flexible PVC Construction: The soft material compresses easily into place without cracking, ensuring a reliable seal every time.

• No Additional Tools Required: Simply press the donut into the joint—no sealants, adhesives, or specialized equipment needed.
