AT310587 Hydraulic Cylinder Seal Kit John Deere 310J 325K Excavator Repair

Description

Professional hydraulic cylinder seal kit AT310587 designed for John Deere 310J and 325K excavator hydraulic systems. This seal kit features a multi-lip piston seal design that provides triple sealing action: primary oil sealing, dust exclusion, and pressure stabilization. The AT310587 seals are made from premium nitrile rubber with fabric reinforcement for high-pressure applications up to 400 bar. Specifically engineered for the boom, stick, and bucket hydraulic cylinders on John Deere 310J and 325K models. The seals feature anti-extrusion rings that prevent gap extrusion under sudden pressure spikes, a common cause of seal failure in excavator applications. Each kit is quality-tested for hardness, tensile strength, and compression set. Compatible with both standard and extended life hydraulic fluids. Installation hardware and fitting instructions included. This seal kit represents the best value for preventive maintenance and emergency repairs on John Deere excavators.
