Sewer and Drainage Pipe Seals and Gaskets
Sewer and drainage systems are a fundamental part of urban infrastructure and buildings. The reliability of these systems depends on the quality of the seals in the pipe joints. The right seal prevents leakage, odour and environmental contamination.
Requirements for sewer seals
Sewer and drainage seals must withstand aggressive wastewater, temperature variations and soil pressure. Key requirements include:
- Chemical resistance — domestic and industrial wastewater contains various chemicals.
- Watertightness — the seal must provide sealing against both the internal flow and external groundwater.
- Longevity — since replacing a seal in underground systems is difficult, a long service life is important.
Why EPDM is chosen
EPDM rubber is one of the most suitable materials for sewer and drainage seals. It shows excellent resistance to water, ozone, UV rays and many chemicals. Its retention of flexibility over a wide temperature range makes it ideal for underground applications.
Sealing principle
Modern sewer pipes are often joined using a rubber ring (gasket). When the pipe is inserted, the seal compresses to form a watertight joint. You can find detailed information about this principle in our article on pipe seals and sealing.
Installation recommendations
- Clean the pipe surfaces before installation.
- Choose a correctly sized seal — too large or small causes leakage.
- Use lubricant if needed to seat the seal without damage.
- Check that the joint is correct.
