The JBB flat seal is a replacement part designed specifically for BB marine cable glands. It is intended to ensure optimum seal between the different parts of the cable gland, preventing the infiltration of water or moisture and guarantee reliable protection against the external elements in the marine environment. This flat seal is manufactured with corrosion-resistant materials and difficult conditions at sea, making it an ideal choice for keeping electrical and mechanical equipment in good working order. It is available in replacement under the REP reference. 1, thus ensuring the compatibility with the cable glands of the BB series.
