Material Composition | Preventing leaks in drain systems | Copper alloy (ASTM B115 compliant) ▲▲▲ (Industry: Steel, Base: Bronze) | 30% higher corrosion resistance than steel (resists chlorine in water) | 20% higher cost than steel alternatives (tooltip: "Copper’s premium cost vs durability trade-off") |
Spring Design | Ensuring valve sealing precision | Helical compression with 0.5mm wire diameter (ISO 2062) ▲ (Base: 0.6mm) | Precise force application for tight seals (tooltip: "0.5mm ensures 15% tighter fit") | Limited compression range vs thicker wires (tooltip: "Optimized for standard washer loads") |
Corrosion Resistance | Humid environments (washer interiors) | Withstands 1000+ salt spray hours (ASTM B117) ▲▲ (Base: 500 hours) | 2x longer lifespan in moist conditions (tooltip: "Outperforms galvanized steel") | Requires periodic lubrication (tooltip: "Copper’s oxide layer needs maintenance") |
Load Capacity | Handling heavy drainage cycles | 50 N max load (IEC 60068) ▲▲▲ (Industry: 30 N, Base: 40 N) | Supports 1.5x heavier loads (tooltip: "Handles high-pressure drain systems") | Heavier than lower-tier springs (tooltip: "Copper’s density may affect installation space") |
Compatibility | Universal washer fitment | Fits 90% of washer models (YICHI certified) ▲ (Base: 70% models) | Reduces replacement costs (tooltip: "Works with major brands like LG/Samsung") | May not fit vintage models (tooltip: "Pre-2010 washers may require adapters") |
Durability | Long-term operational reliability | 10,000 cycles without failure (IEC 60068) ▲▲ (Base: 8,000 cycles) | 25% fewer replacements over 5 years (tooltip: "Outperforms plastic alternatives") | Higher upfront cost vs short-lived alternatives (tooltip: "Balances cost vs longevity") |
