Expansion Plugs (Various Sizes)

The Expansion Plugs are a reusable mechanical pipe plug designed to create a quick, reliable watertight seal in pipe ends. Ideal for low- and medium-pressure water applications, it uses a simple wing nut that compresses the durable rubber body, expanding it securely against the inside of the pipe to form a leak-resistant seal. No special tools are required, making installation and removal fast and convenient.

Manufactured with a durable rubber sealing body, nylon wing nut, and corrosion-resistant hardware, it is suitable for use with PVC, ABS, fibreglass, steel, cast iron, and clay pipe. It is commonly used in fish hatcheries, aquaculture facilities, water treatment plants, plumbing maintenance, leak testing, and temporary pipeline isolation.
