Seal design & function
The Trelleborg 570 fits around the inside diameter of the access hole. The design of the seal provides excellent sealing performance and significant angular deflection possibilities.
Trelleborg 570 is usually used on smooth wall PVC pipes, but small dimensions (DN 25 to DN 90 mm) may also be used with corrugated hoses in dry networks.
DN 25 to DN 90 mm seals accommodate 2 pipe diameters (see sizing chart). The unwanted part of the seal is cut away when used for the larger DN.
Key features & benefits
- Simple and easy to use with either prefabricated or drilled holes
- Excellent angular deflection possibilities
- Easy installation
Material
- Synthetic rubber - Hardness 40±5 IRHD
- Approved in accordance with EN 681-1
- Protected against ozone, available in oil resistance material
