Typical Applications

This 1-1/2" x 1” reducer coupling is ideal for connecting different pipe sizes across a variety of settings. It’s frequently used in residential plumbing, agricultural irrigation, pool systems, and industrial water distribution. The slip-socket design allows for quick solvent-weld installation, ensuring a leak-free fit every time.

Because it’s corrosion-resistant and non-conductive, this PVC fitting performs reliably in indoor, outdoor, and underground environments. It maintains consistent pressure and flow, even when connecting lines of varying diameters — an invaluable advantage for both professional and DIY plumbing projects.

Installation & Handling Tips

For top-tier performance, be sure to follow the best practices below:

• Cut the pipe squarely and remove any burrs.
• Clean the pipe and socket surfaces thoroughly.
• Apply PVC primer to both ends, followed by ASTM D2564 solvent cement.
• Insert the pipe fully and twist ¼ turn to evenly distribute cement.
• Hold in place until the bond sets and wipe off any excess.
• Allow 15 minutes for handling strength and 2 hours for full cure before pressurizing the system.
• Store unused fittings in a dry, shaded area away from direct sunlight.

Carefully following these steps helps create a secure, watertight connection that maintains long-term system performance.
