ProSource 4 in. x 2 in. Flexible Hub Donut

The ProSource 4 in. x 2 in. Flexible Hub Donut is engineered for efficient compression sealing of sewer pipe joints and drain, waste, and vent connections. Designed to fit sockets, bells, hubs, and spigots, this flexible donut delivers a secure, dependable seal to prevent leaks in non-pressurized gravity-flow drainage applications. Constructed from durable PVC material, this hub donut resists degradation and maintains flexibility for straightforward installation in pipe repair and maintenance projects. Note that this fitting is intended specifically for gravity sewer and drainage systems and is not for use in pressurized plumbing applications.
