Copper Fittings (Our Advanced) | High-pressure HVAC systems, commercial buildings | - Material: Copper (99.9% purity, ASTM B115 compliant) - Welding: Automated orbital TIG (▲ 30% less defects vs manual) - Pressure: 420 psi (exceeds ASME B16.9 by 15%) | ▲ Superior corrosion resistance Seamless joints for zero leaks Ideal for high-pressure environments | Higher upfront cost Requires skilled installation for automation |
Copper Fittings (Our Base) | Residential HVAC, light commercial systems | - Material: Copper (99.5% purity, ASTM B115) - Welding: Manual brazing (AWS B7.1) - Pressure: 350 psi (meets ASME B16.9) | Cost-effective Reliable for standard applications Durable long-term | Manual welding may have ±5% joint strength variance Limited to moderate pressures |
Plastic Fittings (Industry Standard) | Low-pressure residential HVAC, indoor use | - Material: PVC (ASTM D1784) - Pressure: 160 psi (ANSI/ASSE 1061) - Weight: 40% lighter than copper | Lightweight Low cost Easy to install | Not rated for high temps/pressures Susceptible to chemical degradation over time |
Stainless Steel Fittings (Competitor) | Marine HVAC, high-corrosion environments | - Material: 316L stainless steel (ASTM A240) - Corrosion Resistance: Resists saltwater (▲ over copper in coastal areas) - Weight: 2x heavier than copper | ▲ Exceptional corrosion resistance High durability in harsh conditions | Higher cost Requires specialized tools for bending/assembly |
Aluminum Fittings (Alternative) | Lightweight HVAC units, temporary setups | - Material: 6063-T5 aluminum (ASTM B221) - Weight: 30% lighter than copper (▲ for mobility) - Conductivity: 60% of copper | ▲ Lightweight for easy transport Cost-effective for short-term use | Prone to corrosion without coating Lower pressure capacity (200 psi max) |
Galvanized Steel Fittings (Another Option) | Industrial HVAC, moderate corrosion | - Material: Galvanized steel (ASTM A653) - Corrosion Resistance: Zinc coating (ASTM A123) - Weight: Heavy (▲ requires sturdy support) | Strong structural integrity Cost-effective for industrial use | Zinc coating wears off over time Heavy, complicates installation |
