Glands IP68 - complete with locknut. Made of polyamide, these glands consist of a body fitted with elastic fins that, when a nut is tightened, tighten concentrically and uniformly around an NBR washer seal, and guarantee an IP68 water tightness and efficient cable retention. The nut being tightened has internal notches that obstruct the fins and make accidental unscrewing impossible. The seals are resistant to ageing, corrosion and oils and remain inert to the material that sheathes the cables. ISO metric thread in compliance with CEI EN 60423.
