Select ISO VG grade from your hydraulic system OEM manual or nameplate — the most common grades are ISO 46 and ISO 68

Optimised for High-Speed Systems

ISO VG 32 low viscosity ensures smooth fluid flow and rapid system response in high-speed hydraulic systems — reducing internal fluid friction, lowering operating temperatures and improving efficiency in high-cycle industrial hydraulic applications.

Anti-Wear Pump Protection

Anti-wear (HM) additive system protects gear, vane and piston pumps from wear under the high contact loads and pressures typical of industrial hydraulic systems — reducing pump wear rates and extending component service life.

Good Oxidation Stability

Good resistance to oxidative degradation helps prevent sludge and deposit formation in the hydraulic reservoir and system — maintaining system cleanliness and consistent hydraulic performance throughout the oil's service life.

Good Low-Temperature Performance

Pour point of -24°C and relatively low viscosity ensures reliable cold-start oil circulation in unheated workshops and outdoor equipment in cooler ambient conditions — particularly relevant for ISO VG 32 which is often specified for cold-environment hydraulic applications.

Rust & Corrosion Protection

Good rust and corrosion protection for hydraulic system components — protecting cylinder bores, pump internals, valve surfaces and reservoir walls from corrosion in the presence of water contamination.

Foam Control & Air Release

Good foam control and air release properties maintain consistent fluid compressibility — ensuring reliable hydraulic system response and preventing the spongy, erratic operation caused by air entrainment in high-cycle industrial hydraulic systems.

High-Speed Industrial Hydraulics

High-speed industrial hydraulic systems where rapid fluid flow and system response are required — injection moulding machines, presses, stamping equipment and other high-cycle industrial machinery specifying ISO VG 32 anti-wear hydraulic oil.

Machine Tool Hydraulics

Precision machine tool hydraulic circuits, CNC machine hydraulics and grinding machine hydraulics where ISO VG 32 is specified for precise, repeatable hydraulic response and low heat generation.

Mobile Hydraulics — Cooler Climates

Mobile hydraulic machinery operating in cooler ambient conditions where ISO VG 32 is OEM-specified — construction, agricultural and materials handling equipment in the Western Cape and Highveld winter where lower viscosity is required for cold-start performance.

Marine & Offshore Hydraulics

Marine hydraulic systems specifying ISO VG 32 anti-wear hydraulic oil — deck machinery, steering gear, hatch cover hydraulics and offshore platform equipment where ISO VG 32 is OEM-specified.

Gear, Vane & Piston Pump Systems

All common hydraulic pump types — gear pumps, vane pumps and piston pumps — in industrial hydraulic power units specifying ISO VG 32 anti-wear (HM) hydraulic oil.

General Industrial Hydraulics

General purpose industrial hydraulic power units specifying ISO VG 32 — manufacturing plant, processing equipment and any industrial hydraulic system where the OEM nameplate or service manual specifies ISO VG 32 HM hydraulic oil.
