Genuine OEM seal ring made specifically for 18mm diameter, 2mm thick protective lenses in laser welding systems. This high-temperature seal ring blocks metallic vapor, spatter, and contaminants that cloud lenses and ruin weld consistency.

Why This Seal Matters for Your Operation:

• Stops Lens Clouding – Seals out metal vapors that permanently coat optics
• Withstands Welding Heat – Rated for continuous 300°C+ environments
• Maintains Shielding Gas Integrity – Ensures consistent weld quality
• Prevents Frequent Lens Changes – Extends protective window life
• Exact 18x2mm OEM Fit – No guesswork, guaranteed compatibility

Replace When You Notice:

• Weld porosity or inconsistency appears
• Visible spatter buildup around lens edges
• Shielding gas flow seems unstable

Maintenance Tip:
Always replace the seal ring when changing lenses— a seal ring can protect a lens from permanent damage.
