Schedule 40 4 In. Compression X 3 In. D Compression Pvc 5 In. Donut Fitting 1 Pk

The Fernco P44U-305 Compression Donut is a flexible PVC ring engineered to create strong, lasting joints between dissimilar pipe materials in sewer and drain-waste-vent (DWV) systems. This donut-shaped fitting connects 4-inch service weight cast iron hub pipe to 3-inch PVC Schedule 40 plastic pipe, making it essential for transitions where cast iron and plastic piping meet underground or in trench applications.

Compression donuts provide flexible, removable connections for sealing joints between different pipe materials and diameters. They accommodate sockets, hubs, bells, spigots and other joint configurations common in drainage systems. The donut ring design is ideal for trench work where space is limited.

Features and Benefits

• Flexible PVC Ring: The donut-shaped design provides compression sealing for sewer pipe joints and DWV connections.
• Corrosion and UV Resistant: Engineered to withstand soil moisture and sunlight, ensuring reliable underground performance.
• Even Pressure Distribution: The donut ring design distributes clamping pressure uniformly across the joint for a consistent seal.
• Removable and Flexible: Allows for repositioning or removal without permanent attachment to pipe materials.
