Version 4 (Focus: Performance & Contamination Control)
In an excavator loader hydraulic cylinder, the 3E6756 functions as the primary dust exclusion device. The 3E6757 acts as a high-efficiency scraper seal for the same system. The 3E6756 removes dry dust and clay before it reaches the rod seal. The 3E6757 handles wet mud and fine sand particles effectively. For applications requiring dual-stage contamination control, the 3E6756 and 3E6757 work as a matched set. The 3E6756 reduces abrasive wear on chrome-plated rods. The 3E6757 minimizes pressure drop across the sealing interface. Both the 3E6756 and the 3E6757 are validated for excavator loader duty cycles.
