- Copper-glass seal bonds insulator, terminal post center electrode together; assures full required voltage at spark gap; gas-tight seal (100% leak proof)
- Multi-rib insulator reduces danger of "flash-over
- One-piece terminal post adds strength
- Resistor reduces radio frequency interference (RFI) and electrode erosion
- Cold-formed steel shell precision rolled threads
- Full Copper Core electrode provides better performance in all conditions
