Non-Asbestos Graphite Gaskets (Our Base) | High-pressure machinery, industrial joints | Material: Non-asbestos graphite (ISO 1401 compliant) ▲ Pressure: 1200 psi (ASTM F1619) Temp Range: -40°C to 400°C | ▲ Non-toxic, cost-effective High temp/pressure tolerance | Lower durability vs. metal Requires flange alignment (±0.1 mm tolerance) |
Non-Asbestos Graphite Gaskets (Our Advanced) | Harsh chemical plants, extreme-temperature systems | Material: Reinforced graphite ▲ Pressure: ▲ 1800 psi (ASTM F1619) Temp: ▲ 600°C Chemical resistance: ASTM D543 (50+ exposures) | ▲ Superior durability ▲ 30% higher pressure capacity vs. Base Chemical inertness | Higher cost vs. Base Stiffer material limits flexibility |
Asbestos Gaskets (Industry Standard) | Legacy industrial systems (phased out) | Material: Asbestos (non-compliant with ISO 1401) Temp: Up to 700°C (ASTM C611) | Historically used for extreme heat resistance | ▲ 0 Health hazards (cancer risk) Banned in most regions (OSHA regulations) |
Metal Gaskets (Stainless Steel) | High-pressure steam, aerospace | Material: 316L stainless steel (ASTM A240) Pressure: 3000 psi Temp: -200°C to 800°C | ▲ Extreme durability ▲ 2x pressure capacity vs. Our Base | Rigid design requires precise flange alignment High cost |
Rubber Gaskets (Nitrile) | Automotive, oil/gas systems | Material: Nitrile rubber (ASTM D2000) Temp: -40°C to 120°C Oil resistance: ASTM D395 | Flexible, cost-effective Resists oil/gas exposure | ▲ 0 Low temp/pressure limits Degrades over time in UV/oxygen |
PTFE Gaskets | Chemical processing, food-grade equipment | Material: PTFE (ASTM D412) Temp: -196°C to 260°C Chemical inertness: ASTM D543 (100+ exposures) | Non-reactive, clean surface ▲ 50% wider temp range vs. Rubber | Brittle at low temps Low pressure capacity (max 500 psi) |
