C. O-Ring Lubrication
An o-ring on the Torch ATC Male Connector requires
lubrication on a regular basis, depending on how
frequently the torch is disconnected and re-con-
nected. 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 tempera-
tures 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 per-
formance or poor parts life.
