A. O-Ring Lubrication
An o-ring on the Torch ATC Male Connector requires lubrication on a scheduled basis. This will allow the o-ring to
remain pliable and provide a proper seal. The o-ring will dry out, becoming hard and cracked, if the o-ring lubricant
is not used on a regular basis. This can lead to potential performance problems.
It is recommended to apply a very light film of o-ring lubricant (Catalog # 8-4025) to the o-ring on a weekly basis.
NOTE
DO NOT use other lubricants or grease, they may not be designed to operate within high temperatures or may contain
“unknown elements” that may react with the atmosphere. This reaction can leave contaminants inside the torch.
Either of these conditions can lead to inconsistent performance or poor parts life.
