COUPLING 1-1/2" MPT

The 1-1/2" MPT Coupling is a durable, threaded plumbing fitting designed to connect two female-threaded components in pond, fountain, irrigation, or low-pressure water systems. Featuring 1-1/2" male pipe threads (MPT) on both ends, this straight coupling is ideal for use with pumps, filters, valves, or inline plumbing where a strong, leak-resistant threaded connection is required.

Constructed from heavy-duty PVC or reinforced plastic, this fitting is built to withstand outdoor elements, UV exposure, and corrosive water conditions. It’s easy to install, reusable, and provides a secure alternative to glued connections when flexibility and maintenance access are needed.
