Product range
LESSO industrial systems: individual product photos, dimensions and technical specifications are presented directly on this page. Select the material, size, pressure class and connection method for the project.
Three systems are covered: basic galvanized KJG, PVC-sheathed waterproof KJG-V and halogen-free polyethylene-sheathed KJG-WV. The inner thermosetting powder layer provides insulation; the source comparison specifies IP67 for the waterproof system and31.6% oxygen index for the halogen-free outer sheath. Tubes can be shaped by hand during installation and are not intended for frequent repeated flexing. Basic, waterproof and halogen-free dimensional tables and all BG/KS/WBG/WD/SP accessory series are included. Inside diameters are reference values; outside diameter controls acceptance. The100# KJG-V outside diameter is left blank because the printed source repeats its inner-diameter value.
