Typical Applications

This 3/4" slip coupling PVC fitting is a trusted solution across numerous plumbing systems due to its versatility and ease of installation:

• Created to connect or extend PVC pipe runs in irrigation, pool plumbing, and water supply lines.
• Commonly used for repairs, retrofits, or system expansions in residential, agricultural, and light industrial applications.
• Excellent for low-pressure water systems or chemical transport applications compatible with PVC.
• Maintains consistent flow alignment and reduces turbulence within pipe systems.
• Lightweight, non-corrosive, and rust-resistant, ensuring dependable long-term use.
• Note: Not suitable for compressed air or gas systems.

Installation & Handling Tips

To achieve a watertight and long-lasting bond when installing this Schedule 40 PVC coupling, follow these best practices below:

• Prepare the surfaces: Clean both pipe ends and the coupling sockets using PVC cleaner to remove debris or oil.
• Prime and cement: Apply primer followed by a generous coat of PVC solvent cement to both the pipe and fitting.
• Join the connection: Insert pipe ends fully into the coupling’s sockets while twisting slightly to evenly distribute the cement.
• Set and hold: Maintain steady pressure for several seconds to allow the joint to set, then wipe away any excess cement.
• Cure before testing: Allow at least 15 minutes for partial cure (two hours for full cure) before pressure testing.
• Storage: Keep unused couplings out of direct sunlight and away from high heat to prevent UV degradation and material fatigue.

Proper installation is the best way to secure a permanent connection capable of withstanding normal service pressures and temperatures.
