Flanged Couplings WSF50

50mm flanged couplings, also known as wall sleeves, are DWV PVC fittings used to create access points in concrete, plastic, fibreglass, or steel tank walls. The rib-free interior allows pipes to pass through smoothly.

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 standard wall thicknesses.

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