Tyton rubber gaskets, also known as Tyton gaskets, are specialized sealing components used in ductile iron pipe systems, particularly in water and wastewater applications. The Tyton joint is a commonly used joint design in ductile iron pipes, characterized by its mechanical joint with a rubber gasket. Tyton gaskets play a crucial role in creating a watertight and secure connection between pipe sections. Here are some key features and functions of Tyton rubber gaskets:

1. Sealing Function: Tyton rubber gaskets are designed to create a tight seal between the spigot (male) end of one pipe and the bell (female) end of another pipe in a mechanical joint. The gasket is compressed between the pipe ends, forming a watertight seal that prevents leakage of water or wastewater.

2. Material: Tyton rubber gaskets are typically made from synthetic rubber materials such as EPDM (Ethylene Propylene Diene Monomer) or NBR (Nitrile Butadiene Rubber). These materials offer excellent resilience, elasticity, and resistance to water, chemicals, and UV exposure, ensuring long-term sealing performance.

3. Profile Design: Tyton gaskets have a specific profile design that matches the geometry of the bell and spigot ends of ductile iron pipes. The gasket features a tapered shape with rounded edges to facilitate easy insertion into the bell end and ensure proper alignment during joint assembly.

4. Compression and Recovery: Tyton gaskets are designed to be compressed between the pipe ends during joint assembly, creating a secure and reliable seal. They exhibit excellent elastic recovery properties, allowing the gasket to rebound and maintain its sealing integrity even after repeated cycles of compression and expansion.

5. Corrosion Resistance: Tyton rubber gaskets provide corrosion resistance, making them suitable for use in buried or submerged applications where exposure to corrosive soils or groundwater is a concern. The rubber material effectively seals out moisture and prevents the corrosion of pipe joints.

6. Temperature and Pressure Ratings: Tyton rubber gaskets are designed to withstand a wide range of operating conditions, including variations in temperature and pressure. They are engineered to maintain their sealing performance within specified temperature and pressure limits, ensuring reliable operation in diverse environments.

7. Installation: Tyton rubber gaskets are relatively easy to install and require minimal tools and equipment. They are placed into the bell end of the pipe before the spigot end is inserted, and the joint is then assembled by pushing the pipes together. The compression of the gasket creates a tight seal, completing the joint.

Overall, Tyton rubber gaskets are essential components of ductile iron pipe systems, providing reliable sealing and joint integrity in water and wastewater infrastructure projects. Their durable construction, ease of installation, and long-term performance make them a preferred choice for pipe manufacturers, contractors, and engineers.
