McAlpine TUN-2 Tundish designed to catch overflow liquids from tanks or cisterns. It features a 50mm diameter and a 19/23mm pipe outlet, compatible with standard plumbing. Manufactured in Polypropylene, it ensures durability and long-lasting performance. The internal sleeve centers and supports the pipe, while the Multifit and Friction Washers create a secure seal. When the compression nut is hand-tightened, a mechanical joint is formed. If a plastic pipe is undersized or out of shape, warming the end may be necessary for insertion over the internal sleeve.
