Product Overview
Genuine ZF 0634303152 O-Ring Seal (277×2.5mm)
Secure the integrity of your ZF transmission’s hydraulic system with this genuine ZF 0634303152 O-Ring. This critical sealing ring, with precise dimensions of 277mm x 2.5mm, is manufactured by ZF to original equipment (OEM) standards, ensuring a perfect fit and a reliable, leak-proof seal in high-pressure applications.
As a dedicated ZF parts supplier and ZF parts dealer, we provide only authentic components that are essential for maintaining optimal transmission performance. A failing O-ring can lead to fluid leaks, pressure loss, erratic shifting, and serious internal damage. This OEM O-ring is made from advanced elastomers designed to withstand transmission fluid, heat, and pressure, guaranteeing a lasting repair.
Key Benefits:
OEM Precision: Exact 277mm x 2.5mm dimensions ensure a perfect fit for specific ZF transmission channels and connectors.
Superior Material: Made from ZF-specified nitrile or fluoroelastomer compound for excellent resistance to automatic transmission fluid (ATF), heat, and pressure.
Prevents Leaks: Creates a robust seal in high-pressure hydraulic circuits, protecting your transmission’s vital functions.
Maintains System Pressure: Essential for ensuring proper operation of clutches, valves, and torque converters.
Guaranteed Compatibility: Designed specifically for your ZF transmission model, eliminating guesswork.

Simple Install Tip
Warning: Always disconnect the vehicle’s battery and depressurize the transmission system before beginning work. Work with clean hands and tools to prevent contamination.
Access & Clean: Locate the connection point where the O-ring is seated. Thoroughly clean the area around the fitting to prevent dirt from entering the hydraulic system.
Remove the Old O-Ring: Carefully disconnect the union or fitting. Use a plastic pick or your fingernail to gently remove the old, hardened O-ring. Do not use sharp metal tools that can scratch the sealing surfaces in the groove or on the mating part. Scratches will cause the new O-ring to leak.
Inspect: Examine the groove for any nicks, burrs, or debris. Clean it meticulously.
Lubricate: Lightly lubricate the new genuine ZF 0634303152 O-Ring with clean automatic transmission fluid (ATF). This prevents it from twisting, rolling, or tearing during installation.
Install: Carefully seat the O-ring evenly into its clean groove. Ensure it is not twisted or stretched.
Reconnect: Re-assemble the connection, hand-tightening first. Use a torque wrench to tighten the fitting to the manufacturer’s exact specification. Over-tightening can deform the O-ring and damage threads.
Check for Leaks: Reconnect the battery, start the engine, and cycle through the gears. Carefully check the repaired connection for any signs of leakage.
