4307370 Accumulator

4307370 accumulator (replacement part 2872035) suits Cummins ISX12, ISX11.9, QSZ13 and Z13 engines. This hydraulic buffer component stabilizes fluid pressure fluctuation inside engine hydraulic circuits to reduce pressure shock on related pipelines and valves. Built with pressure-resistant metal shell and durable internal diaphragm, it maintains stable performance under frequent pressure cycling and high working temperature. It effectively smooths hydraulic impulse and protects system components from impact damage. Standard mounting structure supports convenient disassembly and replacement in workshop service. Two available part numbers bring flexible sourcing choices for Cummins engine repair and overhaul projects.
