Supplier's note

1. Three Technical Breakthroughs:

   • Copper Beads: With copper’s inherent lubricity, these rings reduce friction by 25% compared to traditional steel-only designs.
   • Tapered Profile: The 0.05mm/inch taper ensures a 15% tighter seal under pressure, minimizing gas leakage.
   • Dual-Material Composition: Combining copper and steel alloy achieves 30% higher thermal stability than single-material alternatives.

2. Optimal Version Selection:

   • Base Model: Ideal for standard industrial compressors (e.g., HVAC systems) requiring reliable performance at moderate temperatures.
   • Advanced Model: Tailored for heavy-duty applications like mining equipment, where +15% hardness and 230°C resistance prevent premature wear.
   • Pro Model: Designed for extreme environments (e.g., oil refineries) where tripled chemical resistance and 260°C tolerance ensure uninterrupted operation.

With the Pro Model’s 58.5 HRC hardness, you can handle abrasive particles in harsh industrial gases. Pair this with its tapered profile to achieve a 20% tighter seal than industry benchmarks, directly boosting compressor efficiency.
