Duro Ultra Hydraulic Oil ISO 5

Product Description

DURO ULTRA HYDRAULIC OIL ISO 5 is low viscosity, is a premium anti-wear hydraulic oil with rust, oxidation and foam inhibitors and zinc based anti-wear additives. It promotes excellent cleanliness, longer fluid life, demulsibility and filtering ability even when water contaminated.

DURO ULTRA HYDRAULIC OIL ISO 5 has a long charge life due to the superior quality chemical and thermal stability additive components in the finished oil. Excellent air release properties minimise compressibility and prevent noisy and erratic operation of equipment.


DURO ULTRA HYDRAULIC OIL ISO 5 is for use in hydraulic systems calling for zinc-based anti-wear oils, particularly systems with vane pumps operating at pump pressures above 1000 psi and speeds above 1200 rpm. The exceptional performance of the anti-wear additives in the important areas of high-pressure/high-speed pump protection, anti-rust and corrosion, thermal and oxidative stability and filterability provides a cost-effective product resulting in reduced equipment downtime. It can also be used in other systems where wear rates are high using conventional oils.

DURO ULTRA HYDRAULIC OIL ISO 5 is compatible with other hydraulic oils that contain a zinc based anti-wear system.
