Installation Notes and Tips

Confirm flange style, bolt spacing, and port dimensions before installation. The gasket should match the three-bolt pattern and the 2.25 x 2.25 port opening for proper alignment. Clean both mating surfaces thoroughly so the gasket can seat evenly and seal correctly. For best results, inspect the flange faces and fasteners for wear or distortion before reassembly.
