Description
Product Overview
The Hydro-Gear transmission pump seal is a genuine OEM replacement designed to match the original equipment specifications for a wide range of automatic transmissions. Measuring a compact 1 x 1 x 1 inches and weighing only 1.76 ounces, this seal is constructed from high‑grade polymer compounds that resist heat, pressure, and chemical exposure. It features a precision‑molded lip that maintains a tight seal around the pump shaft, preventing fluid leaks and ensuring consistent hydraulic pressure. The part number 70525 corresponds to the manufacturer’s catalog, guaranteeing compatibility when cross‑referenced with the vehicle’s service manual.
Usage
This seal is intended for use in automotive repair shops, fleet maintenance facilities, and by DIY owners performing transmission overhauls. It excels in environments where the pump operates under high temperature and pressure cycles, such as daily commuting, towing, or performance driving. Installers should verify the correct part number against the vehicle’s VIN and follow the service manual’s torque specifications for optimal performance.
