Rock Oil HLP 32 Hydraulic Oil
Rock Oil HLP 32 Hydraulic Oil
ISO 32 viscosity grade Hydraulic Oil from Rock Oil.
32 grade refers to the thickness or ‘viscosity’ of the hydraulic oil; the higher this number, the thicker the oil. You may see these terms written as VG 32, or AW 32, which just means ‘anti-wear.’
Product Specification
Rock Oil HLP 32 Hydraulic Oil
Rock Oil HLP 32 Hydraulic Oil offers the following benefits:
- Proven performance,
- Outstanding thermal and oxidative stability,
- Superior hydraulic stability,
- Good demulsibility,
- Excellent rust protection and lower filter blockage.
Rock Oil HLP hydraulic oils are made from the finest virgin oils and are treated with the most advanced additives available. Meeting the industry hydraulic standard of DIN 51524 part 1 & 2, these mineral hydraulic oils are extremely popular among all sectors where hydraulic fluid is required.
HLP oils exceed 2000 Hour TOST (Turbine Oxidation Stability Test) life, over TWICE the life of many conventional mineral oil based hydraulic fluids.
*Demulsibility measures an oils ability to release water. Water that enters a hydraulic system can mix together with the oil and cause dust, grit, and dirt to collect, which can adversely affect the operation of valves, and pumps. It can also increase wear and corrosion, promote fluid oxidation, deplete additives, and plug filters. Highly refined mineral oils permit water to separate or demulsify readily.
Performance specifications and approvals of Rock Oil HLP 32 Hydraulic Oil:
- DIN 51524 part 1 & 2
- Denison HF-0
- Bosch Rexroth RD90220
Use Rock Oil HLP 32 where your machine or vehicle asks for an anti-wear hydraulic oil of a 32 thickness, or where a medium-weight hydraulic oil is required.
