Seal Ring Installation Note
Caution:
^ If installation is performed without using the SST, the seal ring will be damaged and deformed, resulting in an incorrect installation. Always use the SST to install the seal ring.
1. Temporarily install the seal ring to the pipe so that the seal ring is even with the flange.
2. Install the SST to the seal ring so that the SST is even with the flange.
3. Press in the seal ring by tapping the SST using a plastic hammer until the seal ring contacts the flange.
