This elevator hydraulic cylinder packing seal kit is designed as a direct replacement solution for legacy National Wheel-O-Vator (NWOV) systems originally equipped with OLS GMV cylinders featuring a 70mm plunger diameter. It is engineered to restore proper sealing performance within the hydraulic jack assembly, helping maintain smooth operation and consistent system pressure.

Manufactured from high-quality sealing materials suited for hydraulic elevator applications, this kit includes the necessary packing components to service the cylinder head assembly. It is intended for use during scheduled maintenance or overhaul of compatible in-ground or above-ground hydraulic elevator cylinders. The seal components are precision-matched for 70mm plungers to ensure correct fit and reliable performance in compatible NWOV installations.

Proper installation by qualified elevator personnel is essential to ensure safe and reliable operation. All hydraulic system service and seal replacements should be performed in accordance with applicable codes, manufacturer standards, and jobsite requirements.
