Typical Applications
The 1” x 3/4” PVC reducer is ideal for reducing pipe size transitions in both residential and commercial projects. It provides smooth, leak-free flow transitions between different diameters in systems where consistent water pressure is a top concern.
Common uses include:
- Residential plumbing and irrigation systems
- Pool and spa water lines
- Hydroponic and greenhouse systems
- Agricultural irrigation and watering systems
- Industrial and municipal water distribution
PVC’s corrosion-resistant properties make this coupling suitable for both above-ground and underground installations, maintaining dependable performance over time. However, it’s not recommended for air or gas applications.
Installation & Handling Tips
Secure, long-lasting connections are simple when you follow these best practices for installation:
- Cut the pipe ends squarely and remove any burrs or debris.
- Clean both the inside of the sockets and the outside of the pipe with a dry, lint-free cloth.
- Apply PVC primer to both surfaces, then use an ASTM D2564-approved solvent cement.
- Insert the pipe into the socket with a ¼-turn twist for even cement distribution.
- Hold the connection for several seconds while the bond sets, wiping away excess cement.
- Allow at least 15 minutes for handling strength and two hours for full curing before testing.
- Store unused fittings in a shaded, cool area to prevent UV degradation before use.
