Naylor Densleeve is a plain-ended vitrified clay pipe joined by the use of polypropylene couplings and elastomeric seals. Available in nominal diameters 100, 150, 225 and 300mm, Densleeve is manufactured to British Standard BS EN 295 and holds WSAA certification. Also available in the range are bends, junctions and fittings.
Without the requirement for salt-glazing, Densleeve pipes and joints are resistant to attack from substances commonly encountered in sewers. As a plain-ended joint system is used, Densleeve also allows for pipe to be cut to length on-site with minimal waste.
