Typical Applications
This 4" PVC cap is trusted for a variety of plumbing and water-handling systems thanks to its durability, corrosion resistance, and easy installation. Some common use cases include:
- Residential and commercial plumbing systems
- Irrigation and agricultural water lines
- Pool and spa circulation systems
- Industrial low-pressure water handling

Installation & Handling Tips
For top-tier performance, be sure follow to the best practices for solvent-weld installation:
- Clean and dry the pipe end before applying primer or cement
- Use PVC primer, followed by solvent cement, for a secure bond
- Push the cap fully onto the pipe and hold briefly to prevent push-back
- Allow full curing time before testing or pressurizing the system
- Do not exceed the rated temperature or use Schedule 40 PVC for compressed air or gas lines
Taking these steps helps maintain system integrity and reduce leak risks for DIY and professional installers alike.
