Any dirt should be removed from socket and seal before the pipe is inserted. The necessary lubricant Cordes GM-95 is applied liberally by hand, beginning at the socket radius and going as far as about the middle of the socket. This procedure ensures that the pipe can be inserted without problems. Observe EN 1610 when laying the pipes.Material:CK-seals are fabricated from styrene butadiene rubber (SBR). The use of SBR has proven its worth in rainwater and wastewater applications due to its excellent sealing characteristics.Note: We recommend using seals made of nitrile butadiene rubber (NBR) for applications involving mineral fuels such as oils, petrol or similar.
Wedge-shaped sliding seals CKThe long-lasting, secure joint between concrete and reinforced concrete pipes, jacking pipes, egg-shaped profiles, box culverts as well as pipes and connections of all kinds in sewer construction.Benefits:•The wedge shape of the CK-seals guarantee secure and reliable centering during insertion.•The use of CK-seals means reliable, long-lasting joints between concrete pipes as per EN 1916 and DIN V 1201 as well as jacking pipes, frame apertures and egg- and mouth-shaped profiles.•For higher requirements we offera co-extruded version. (...more info >)•Secure fit and problem-free installation.•CK-seals are available in a variety of cross-sections and can thus be adapted to a number of different gap sizes.•Various geometries for a variety of applications CK-seals are subject to constant monitoring by external inspection organizations in Germany and across Europe. They comply with the requirements of EN 1916, EN 681-1, QR 4060 (FBS quality guideline) and other applicable quality standards.Assembly:CK-seals are fitted to the spigot and pressed tight against the connecting shoulder (raised edge) or in a chamber (notch).
