Welcome to the homepage of NIPPON ACCUMULATOR CO.,LTD.

Thank you very much for usually granting your special patronage of using NACOL products.
At the time of shipment of replacement bladder to the oversea customer, NACOL had attached the rust prevention oil, but we stopped this attachment on March 31, 2010.

Please use the NBR oil or IIR grease attached to the replacement bladder instead of the rust prevention oil.
