Scope
This schedule specifies the requirements for the CONNEX-Junction as manufactured by Funke Kunststoffe GmbH for connecting DN160 and DN200 (OD) laterals made of clay, solid wall plastics and structured wall plastics. Adapters are required for clay and structured wall plastics laterals. The wall thickness of the sewer pipe must be between 4.0mm and 31.8mm.
Connection can be too to solid wall plastics, gravity sewers and other materials of suitable wall thickness, such as glass reinforced plastics (GRP) and ductile iron (DI).
This Assessment Schedule applies to the use of the CONNEX-Junction with plastic sewer pipes of stiffness SN2 (SDR51) to SN8 (SDR34).
Product Description
The body of the CONNEX-Junction comprises of upper and lower moulded PVC-U sections. The lower section locks into the sewer pipe and the upper section screws into the lower section. The angular
adjustment of the socket ranges from 0° to 11° which allows up to 5° adjustment for deflection of the pipe and up to 6° to compensate for ground settlement.
EPDM seals are located between the lateral and upper section, upper section and lower section, and the sewer pipe and lower section. The latter seal is fixed to the lower section by adhesive at the factory. The adhesive ensures the seal remains in position during the installation process and does not serve any function after installation is complete.
During installation, the lower section is held in place by retention clips before being locked to the sewer pipe using a PVC-U screw ring and shaped spacer ring.
