6 Months Factory Warranty
Our OEM-spec hydraulic seal kits are engineered for leak-free performance and long service life in harsh worksites. Each kit is assembled from premium compounds (NBR/HNBR, PU, PTFE) and matched to factory tolerances to maintain correct sealing under high pressure and temperature cycles—preventing bypass, cavitation, and premature wear. Every set is bench-tested for extrusion resistance, compression set, and lip integrity to ensure stable cylinder performance in dust, heat, and vibration. With rugged materials and a factory-backed warranty, these kits reduce maintenance downtime, extend cylinder and rod life, and keep machines productive across construction, mining, and on-road applications.
