Prevent internal oil bypass and maintain absolute powertrain system pressures with our Premium 4804409 Dynamic Sealing Rings for VOLVO EC210B, EC240B, and EC300D excavator series. Get direct factory pricing, bulk B2B discounts, and fast global air express shipping from China's leading mechanical parts supplier today!
Prevent Internal Pressure Drop, Lock In Fluid Isolation. Failed seal ring triggers fluid leakage and pressure loss, resulting in insufficient lubrication and premature part wear. This high-performance sealing ring stably isolates oil fluid, keeping internal pressure normal to protect Volvo D4D/D6D/D6E/D7E engine powertrain.
High Wear-Resistant Fluorocarbon Material Resist high temperature cracking and bubbling, durable under long-time hot oil immersion.
Optimized Hydrodynamic Lip Design Low friction heat generation, excellent oil scraping and sealing performance.
Super Elastic Recovery Property Low compression deformation, keep steady sealing tension against violent vibration.
Outstanding Chemical Stability Immune to oil additives and exhaust gas corrosion, long service lifespan.

Sealing ring must be replaced when disassembling timing and shaft assembly. Inferior seals easily fail and cause hidden engine damage. Repair workshops and parts wholesalers suggest stocking genuine 4804409 seals. Match with related sealing rings, shaft collars and oil seals to form complete overhaul parts set.
Engine oil pressure gradually declines under load, unable to reach standard working pressure
Oil oozes from timing case seam, contaminating surrounding transmission components
Sealing lip hardens and wears thin, losing original elastic sealing ability
All models for compatibility reference only. Premium sealing ring effectively locks internal fluid pressure, eliminates leakage faults and extends service life of engine rotating and transmission parts.
