DETAILED DESCRIPTION
Corrugated ribs to prevent flashover; high dielectric strength; proper heat transfer; eliminates combustion gas leakage; greater spark and heat transfer; improved anti-fouling; corrosion-resistant.Triple gasket-sealing process virtually eliminates gas leakage past the shell99% highly pure alumina silicate insulator enables use of longer insulator noses to reduce foulingThree-step trivalent-plating process uses silver chromate and zinc for maximum corrosion resistance
