Castrol Lubricants

Hyspin VG 68

The Castrol HyspinTM VG hydraulic oil range is based upon highly refined mineral oil enhanced with rust and oxidation inhibitors.

Castrol Hyspin VG has been specially formulated to provide outstanding protection against rust and oxidation while demonstrating good lubricity. Castrol Hyspin VG is also referred to as a ”R & O" (Rust and Oxidation) hydraulic oil. This range is designed for use in hydraulic systems which do not need anti-wear performance but where a degree of rust and oxidation resistance is desirable. It is also suitable for pumps which contain silver-plated components. The Hyspin VG range is fully compatible with elastomer materials commonly used for static and dynamic seals, such as nitrile, silicone and fluorinated (e.g. Viton) polymers.
    Hyspin VG is classified as follows:
  • DIN 51502 classification - HL
  • ISO 6743/4 - Hydraulic Oils Type HL
  • Good thermal and oxidative stability leads to longer operating life, reduction in lubricant costs and minimises
    • deposit formation giving a cleaner system.
  • Good protection of yellow metal and ferrous components helps maintain and prolong equipment life.
  • Excellent water separation and hydrolytic stability means reduced down time through prolonged lubricant life and increased equipment reliability.
Hyspin AWS grades meet the requirements of:
  • DIN 51524 Part 2
  • Cincinnati Lamb (Milacron) P 68-69-70
  • Denison (Parker Hannafin) HF-0
  • US Steel 126 & 127
  • Eaton (formerly Vickers) I-286-S & M-2950-S
  • Bosch Rexroth RE90220
