How To Make A Ring Seal Joint (Video)

Creating a ring seal joint for a soil pipe is a simple but essential process to ensure a secure and leak free connection. This guide will walk you through the steps and offer tips to make the job easier and more efficient.

Understanding the Ring Seal Joint

Soil pipes typically come with:

• 1 Plain End: Features a factory-made chamfer for smooth insertion.
• 1 Socketed End: Contains a rubber seal for creating a watertight and airtight joint.

When a soil pipe is cut to customise its length, the plain end loses its factory-made chamfer. You’ll need to recreate this chamfer to allow the pipe to slide into the fitting without dislodging the rubber seal.

Tools and Materials Needed

• Fine tooth saw (or a standard saw)
• Deburring tool or file
• Silicone lubricant
• Gloves (optional, for a cleaner application)

Step-by-Step Guide to Making a Ring Seal Joint

1. Cut the Soil Pipe

• Use a fine-tooth saw for a clean, straight cut. This ensures the pipe will fit snugly into the socket.
• After cutting, inspect the edge to ensure no cracks or uneven edges are present.

2. Remove Burrs

• Use a deburring tool or sandpaper to smooth out any burrs around the cut edge. Burrs can interfere with the seal and compromise the joint.

3. Create a Chamfer

• File the cut edge in a diagonal motion to create a smooth, angled chamfer.
• The chamfer allows the pipe to slide easily into the fitting without damaging or dislodging the rubber seal. Aim for a consistent angle around the entire edge.

4. Apply Silicone Lubricant

• Spray or apply silicone lubricant generously around the chamfered end.
• This reduces friction during assembly, making it easier to push the pipe into the socket.

5.  Assemble the Joint

• Align the chamfered end with the socketed fitting.
• Push the pipe firmly into the fitting until it reaches the internal stop. The rubber seal will compress around the pipe, creating a watertight and airtight connection.

Tips for Success

• Use Proper Tools: A fine-tooth saw provides a cleaner cut, making it easier to create a smooth chamfer.
• Ensure Consistency: The chamfer should be even all around the pipe edge for a secure fit.
• Lubrication is Key: Silicone lubricant prevents the rubber seal from being dislodged and reduces the effort needed to push the pipe into place.
• Test the Joint: After assembly, test the joint by pouring water through the system to ensure there are no leaks.

When to Recreate a Chamfer

Always recreate the chamfer after cutting a soil pipe, as it ensures the pipe slides smoothly into the fitting without damaging the rubber seal. This step is critical for achieving a proper ring seal joint, whether working on new installations or repairs.

By following these steps and tips, you’ll have a strong and reliable ring seal joint for your soil pipe system!
