Accumulators, Inc. now offers a full line of accumulator safety blocks, used to safely isolate and discharge accumulator pressure. Many design and safety codes require safety blocks on all accumulators in order to qualify for certification; our safety blocks will surpass those requirements. Our safety blocks will fit any size accumulator up to 40 gallons, with any oil port thread. The blocks are rated to 5000 psi working pressure and will accommodate bladder, piston, diaphragm and float type accumulators, among others.
