A specific type of connector designed for creating a watertight seal where a four-inch nominal diameter polyvinyl chloride (PVC) pipe needs to pass through a tank, container wall, or other barrier. This component typically consists of a fitting that inserts into a pre-drilled hole, along with a gasket or O-ring to ensure a leak-proof seal, and a nut that tightens to secure the fitting in place. For example, it’s frequently used to connect plumbing to a water tank, pond liner, or industrial container, allowing fluids to flow in and out without leakage.
The utility of this type of connector lies in its ability to provide a robust and reliable means of fluid transfer while maintaining the integrity of the structure it passes through. Its resistance to corrosion and chemical degradation makes it suitable for a broad range of applications, including water treatment, aquaculture, and various industrial processes. Historically, similar sealing solutions relied on metal fittings, which were susceptible to rust and degradation. The advent of PVC alternatives offered a lighter, more durable, and cost-effective solution.
