Hydraulic Accumulators | McMaster-Carr

These accumulators come with a charge of nitrogen and are ready to use. They help a system maintain a constant pressure during pump failure. Mount accumulators within 25° of vertical. UN/UNF (SAE) thread connections have straight threads and are also known as O-ring Boss fittings.. Note: For safety, do not disassemble accumulators while they're under pressure.

Bladder damage can occur if the nitrogen precharge pressure falls below 35% of the maximum working pressure. For constant monitoring of nitrogen pressure or for accumulators used with a nitrogen back up bottle, the top of the accumulator is drilled and tapped with a 1/2" N.P.T. port and the Dynac charging valve parts are eliminated.
