The seal under the flange collar d160 made of EPDM material is an essential element for the tightness of flange joints in PVC-U pipes of 160 mm diameter. Correct seating of the seal eliminates leaks even under permanent operating pressure.
EPDM (ethylene propylene diene rubber) exhibits excellent chemical resistance to chlorine, disinfectant chemicals, ozone and weather influences. The material is flexible over a wide temperature range and does not lose its elasticity even after years of operation.
The seal is recommended to be replaced at every disassembly of the flange or when leakage is detected in the flange joint. The original size d160 guarantees a precise fit and even tightening of the flange bolts.
