Laminated insulating rings eliminate all metal to-metal contact,insulating rings provide 35 million ohms resistance across the union O-ring in male sub provides a positive primary seal Seal ring in female sub provides a positive secondary seal

Insulating rings.O-ring.and seal ring can be replaced to extend union life
