        After each use, rinse the sleeve knots of the suit with clean fresh water to free the ring grooves from sand and salt crystals.<\/div>\n<\/li>\n
      • \n
        Store the suit flat or hung on a special hanger, avoiding sharp bends directly in the area where the polyurethane ring is glued.<\/div>\n<\/li>\n
      • \n
        Before installing Waterproof Ultima Twist, check the elasticity of the O-rings and lubricate them with a thin layer of silicone lubricant as a precaution.<\/div>\n<\/li>\n<\/ul>\n
