Product catalog summary
Introduction
Eaton introduces Guardian Seal, a new corrosion-resistant plating technology for Walterscheid carbon steel tube fittings. This technology addresses the demand for improved corrosion resistance, enhancing equipment performance and reducing costs.

Corrosion Resistance
Guardian Seal provides protection against red corrosion for a minimum of 720 hours, offering seven times greater protection than industry standards. It creates a barrier to control oxidation, minimizing system integrity threats, safety risks, downtime, and replacement costs.

Plating Evolution
The evolution of plating technology includes:
  • Pre-2008: Hexavalent Chrome (Yellow/Silver Optics)
  • 2008-2012: Hexavalent Chrome Free Plating (Bright Silver Optics)
  • 2013 and Beyond: Guardian Seal with micro particle impregnation (Bright Silver Optics)

New Standard
Guardian Seal becomes the standard plating for Walterscheid metric tube fittings, fully interchangeable with existing products without requiring inventory changes. Assembly and torque requirements remain unchanged.

Market Applications
Guardian Seal is suitable for demanding applications in sectors such as Agriculture, Alternative Energy, Construction, Mining, Manufacturing, Mobile Material Handling, Offshore & Marine, Oil & Gas, and Transportation.

Protection Barrier
The plating process involves:
  • Galvanic zinc plating
  • Passivation of the zinc layer
  • Impregnation with organic micro-particles
  • Cross-linked polymerisation of the top layer
This results in a durable, corrosion-resistant layer.

Performance
Guardian Seal meets or exceeds various standards, including VDMA24576 K5, SAE J514, J1453, and DIN EN ISO 8434. It is environmentally friendly, nickel-free, solvent-free, and compliant with RoHS, ELV, and REACH requirements. It offers superior friction characteristics compared to zinc-nickel plating.

Conclusion
Guardian Seal provides an advanced, almost impermeable protection layer, ensuring extended equipment life and resistance to corrosion-inducing chemicals.
