Hydraulic Pump Parts SEAL KIT A4VTG90

This A4VTG90 hydraulic pump seal kit is a full repair replacement set tailored for Rexroth A4VTG90 axial piston pumps. It covers all core sealing components needed for routine pump overhaul and leakage troubleshooting, perfectly matching the original pump internal structure and installation dimensions.

The kit includes complete dynamic and static seals, such as high-pressure O-rings, shaft seals, backup rings and wear-resistant sealing gaskets. Every component adopts high-grade rubber and polymer materials to adapt to harsh hydraulic working environments.

Engineered for extreme working conditions, these seals deliver stable resistance to high pressure, oil corrosion and temperature fluctuation. They effectively prevent internal and external hydraulic oil leakage, maintaining consistent pump volumetric efficiency and system working stability.

Precision manufacturing ensures tight tolerance and perfect fitting without modification during installation. It solves common pump faults including shaft seal leakage, joint seepage and pressure drop, extending the overall service life of the A4VTG90 hydraulic pump.

Suitable for engineering machinery and industrial hydraulic equipment equipped with A4VTG90 pumps. Standard packaged with complete accessories, this seal kit is a reliable cost-effective spare part for daily maintenance and professional pump repair.
