The conductive ring (9) is a conductive metal contact ring, not a sealing o-ring. To reduce the risk of fire, explosion, or electric shock:
•Do not remove the conductive ring except to replace it.
•Never operate the gun without the conductive ring in place.
•Do not replace the conductive ring with anything but a genuine Graco part.
