Technical overview

PREBAR T-Piece Flat is a factory-manufactured PVC junction designed to connect three PREBAR PVC Waterstop runs at a horizontal T-intersection. It is precision manufactured and ready to be heat welded directly to PREBAR PVC Waterstop rolls using hot air welding equipment, so the tee arrives as a factory-formed unit instead of being fabricated on site. It is available in 150mm and 250mm and in external and internal corner types. Forspec publishes no Technical Data Sheet for the prefabricated fittings and the range leaflet states no standard, test method or accredited certificate for them, so no performance figures are published against this product.
