How to install the glass seal of the distribution box

To install a distribution box seal, insert the seal from inside the box, secure it with a nut from the outside, and push the pipe through the properly sized tear tab.

Step-by-Step Installation

1. Select the Correct Pipe Size Identify the inlet or outlet hole you will use and determine the pipe size. Most distribution box seals have tear tabs for multiple pipe sizes. Do not cut the seal; only tear along the designated lines to match your pipe size . 2. Prepare the Seal Use a key, screwdriver, or similar tool to start the tear tab for the correct pipe size. For corrugated pipes, remove the 4" tear-out carefully and cut between the raised ribs on the back of the seal if needed . 3. Insert the Seal From the inside of the distribution box, push the seal into the hole. Ensure the seal is oriented correctly, especially for pipes smaller than 4 inches, so it faces the right side up . 4. Secure the Seal From the outside of the box, screw the nut onto the seal to hold it firmly in place. Check that the seal is tight and not loose to maintain a watertight fit . 5. Insert the Pipe Push the pipe through the seal carefully. The flexible seal will create a watertight connection around the pipe . 6. Stabilize the Seal (if applicable) Some seals have stabilizing feet that snap into sockets at the base of the box. Ensure these are properly engaged to prevent movement .

Tips and Considerations

• Always follow the manufacturer's instructions for your specific distribution box model.
• Avoid cutting the seal except where indicated for corrugated pipes.
• Ensure the seal is fully seated and the nut is tightened to prevent leaks.
• For larger pipes (6 inches), the seal may already be pre-cut, simplifying installation . By following these steps, you can ensure a secure, watertight installation of the distribution box seal, maintaining the efficiency and longevity of your drainage or septic system .
