Waga MULTI/JOINT 3207 Plus threaded outlet end cap restraint DN50-400

  Data Sheet |   Product Range | Instructional Video

The Waga MULTI/JOINT 3207 Plus wide range threaded end cap provides a reliable, tensile-restraint mechanical closure for utility and industrial piping systems. Engineered by Georg Fischer Waga N.V. for water, wastewater, and gas applications up to 16 Bar, this fitting incorporates an integrated threaded outlet (3/4 inch to 2 inch) to facilitate air release, pressure monitoring, flushing, or auxiliary service line connections. Its universal design spans nominal diameters from DN50 to DN400, providing up to 43 mm of outer diameter tolerance to accommodate diverse pipe materials without dismantling or pipe preparation.

Constructed from high-grade ductile cast iron EN-GJS-450-10 (GGG 45), the fitting body is fully protected with a Resicoat RT 9000 R4 fusion-bonded epoxy coating applied to a minimum thickness of 250 micrometres in accordance with GSK standards. This corrosion-resistant barrier withstands chemical exposure across pH 2 to 13 and ensures dielectric insulation in underground soil environments. Mechanical restraint is delivered through patented Uni/Fikser gripping teeth manufactured from marine-grade stainless steel AISI 316 (A4), which securely lock onto rigid and flexible pipe materials including PEHD, PVC-U, ductile iron, cast iron, steel, and GRP.

Installation is engineered for field efficiency and operational longevity. The fitting accommodates angular deflection up to plus or minus 8 degrees per socket, absorbing ground movement and pipeline misalignment. Fasteners feature Lubo dry anti-friction coating on stainless steel bolts to completely prevent thread galling and cold-welding during torque application, allowing easy re-tightening or reuse. Delivered with factory-installed hygiene end caps, the Waga MULTI/JOINT 3207 Plus ensures contaminant-free commissioning for potable water distribution, natural gas transmission, and industrial fluid transport networks.
