Stitt S-R407ll-2 Industrial Shielded Spark Plug

Stitt S-R407ll-2 Industrial Shielded Spark Plug. Iridium Alloy Electrode: Resistant to high temperatures and gas corrosion, ideal for biogas and coking gas conditions. Ultra-Long Service Life: Continuous operation for 8000 to 12000 hours, significantly longer than copper core plugs. High-Temperature Resistance: Insulating ceramics withstand temperatures exceeding 1200 degrees Celsius. Anti-Carbon Deposition: Multi-claw ground electrode design prevents carbon buildup and pole breakage. Built-in Damping: High resistance damping prevents ignition interference with unit controllers. Corrosion Resistant Coating: Optional NP anti-corrosion coating available for high-sulfur gas sources. Precision Thread Specification: M18x1.5 thread with 27mm hexagonal sides for standard industrial assembly.
