Liquid-O-Ring 765 “Grease Seal” is a series of specialized wireline lubricants and sealants. These products are
manufactured polymer sealants that maintains a 16-20 viscosity at the recommended temperature range. Liquid-O-Ring 765 “Grease Seal” provides the necessary corrosion inhibitors to effect long range protection to the wireline. Liquid-O-Ring 765 “Grease Seal” is inhibited against the corrosive effects of acids, caustics, salt water,
and H2S.If the operator knows the approximate temperatures in which his unit will be operating, a specific Liquid-O-Ring 765 “Grease Seal” may be ordered which will sustain its viscosity at the operational temperatures. The Liquid-O-Ring 765 “Grease Seal” series of products allow the operator to be more selective in choosing a product to meet his operating conditions.
Liquid-O-Ring 765 “Grease Seal” is applied to grease injection control heads and cable lubricators. Liquid-O-Ring 765 “Grease
Seal” is manufactured for use in arctic conditions. Inhibitors and additives used are designed to
be compatible with products used under arctic conditions.
BENEFITS:
▪ Maintains viscosity at temperature range
