When using a soft patch, how far should the rubber extend beyond the split?

When using a soft patch, the rubber should extend beyond the split by 2 inches. This requirement is crucial for ensuring an effective seal and maintaining the integrity of the patched area. The 2-inch extension allows for adequate coverage of the damaged section, reducing the likelihood of leaks or failures that could occur if the patch were too short. The material needs enough overlap to securely hold the patch in place and withstand any stress or movement that might take place around the split, ensuring the durability and reliability of the repair over time. This approach enhances the overall safety and functionality of the system being repaired.
