Flanged Couplings WSF100

100mm flanged couplings, also known as wall sleeves, are DWV PVC fittings used to create pipe entries in concrete, plastic, fibreglass, or steel tank walls. The rib-free interior allows pipes to pass through without obstruction.

PVC solvent weld ‘blue glue’ bonds PVC pipes and fittings to the coupling, ensuring a strong and watertight connection.

These couplings are suitable for casting into concrete tanks, securing the coupling within the concrete structure of thicker tank walls for large-scale installations.

Flanged couplings are used to fix Nobis Products’ Septic Tank Inlet and Outlet Fittings into septic tanks.
