Hyspin™ HLP-Z
Castrol Hyspin HLP-Z is primarily for use in hydraulic equipment
but is suitable for other duties in which lubricants with good
oxidation stability and lubrication performance are required.
e quality of its base oils and additives permits the application
of Hyspin HLP-Z in lightly loaded gears and for use as
circulating oil in applications where a rust and oxidation
inhibited oil is required.
e range is fully compatible with elastomer materials commonly used for
static and dynamic seals, such as nitrile, silicone and fluorinated (e.g., Viton)
polymers. e Castrol Hyspin™ HLP-Z range is based upon highly refined mineral
oil enhanced with a stabilized zinc additive system.
