- Thread both components into the coupler by hand.
- Tighten securely using a wrench on the hex body.
- Avoid overtightening to prevent thread damage.
- Pressurize the system and inspect for leaks.
Important: Verify compatibility with your system's thread sizes and operating pressure requirements before installation. Always ensure the fitting's pressure rating meets or exceeds system operating pressure.
Maintenance Recommendations
- Inspect threaded fittings regularly for leaks.
