Ceramic Seal-On Extensions Extend Spark Plug Life In Demanding Applications

Engine laboratory tests have shown that when a tight fitting spark plug boot is used, spark plug life is increased. Now BG introduces a composite ceramic PTFE extension that incorporates a PTFE coated Viton® O-ring for increased sealing pressure. Because the voltage necessary to “flash-over” the plug insulator is increased, spark plugs will operate at larger gaps that previously resulted in plug failure. . .

  • High alumina ceramic prevents dielectric breakdown due to corona cutting.
  • Viton® O-ring increases sealing pressure, yet makes extension easier to install.
  • DS™ Connector uses a double spring and will not loosen like Rajah types.
  • Model available for use with silicone hose (stud connection).
