NACOL Bladders are seamless one-piece molded bladders.The bladders which are assembled to NACOL Bladder Type Accumulators are seamless one-piece molded bladders except those designated models (part of R/U/H Series).Seamless one-piece molded bladders do not have seamed parts which result in the stress concentration, so they can remain stable to be used for a long time.In general, the seamed parts of special rubber material is inferior to the seamed parts of nitrile rubber in adhesion and durability. But NACOL bladders are seamless one-piece molded bladders, so you do not have to worry about the seamed parts. NACOL pleated bladders prevent bladder damage due to the bladder's turning up (U-turn phenomenon). NACOL bladder forms a triangular "stelliform" pillar vertically owing to the pleated structure, and the pillar suppresses the bottom area of bladder to rise up by buoyancy. (U-turn phenomenon) The plateau at the bottom of the bladder prevent the bladder damage. Plateau reinforcement in the bladder prevents it from being damaged by sharp bending in the bottom portion of the bladder.when gas is chargednatural shape1/2 compression1/4 compressionSafety VentStandard Hanging ToolSafety Vent14Safety VentStandard Hanging Tool (Eye Nut)Bladder
