HYDAC replacement bladder with M50x1.5 gas valve, for accumulators from 2.5 to 50 litres.
Replacement bladder for HYDAC bladder accumulators, with an M50x1.5 thread on the gas valve body. On HYDAC SB330 and SB400 accumulators this is the standard connection on the 50 litre size; on smaller volumes it is the alternative to the 7/8"-14 UNF valve.
The bladder separates the nitrogen from the oil. Frequent loss of pre-charge or oil coming out of the gas valve are the usual signs of a failed bladder.
Choose by the accumulator volume and check the gas valve thread before ordering: the bladder with 7/8"-14 UNF valve is a separate item.
