HYDREX AW hydraulic fluids start with the patented HT purity process to produce 99.9% pure, crystal clear base oils.

Product Description


Petro-Canada’s HYDREX AW hydraulic fluids are advanced formula, long life, anti-wear fluids designed for high performance hydraulic systems to provide excellent operating and maintenance benefits for increased productivity. HYDREX AW takes your equipment to higher levels of performance. HYDREX AW hydraulic fluids start with the patented HT purity process to produce 99.9% pure, crystal clear base oils. By removing the impurities that can hinder the performance of competitive conventional oils, and blending in our specialty additives, HYDREX AW retains its ‘fresh oil’ properties longer providing resistance to oxidative breakdown and outstanding wear protection.

Features and Benefits

1. Outstanding oxidation and thermal stability

• Longer oil life which helps extend drain intervals for reduced change-out costs and less reservoir exposure to external contaminants
• Resists degradation (breakdown) in high temperatures reducing need for additive top up
• Decreases varnish build up that can interfere with servo and directional valve operation
• Minimizes harmful sludge build up in the reservoir that can lead to shortened oil life and equipment wear

2. Exceptional anti-wear protection

• Extends equipment life
• Reduces maintenance and mechanical failure
• Protects equipment being driven longer, harder and faster in tougher conditions
• Improves operating reliability over a wide range of pressure

3. Improved rust and corrosion prevention

• Iron and other metal components protected against water damage

4. Excellent water separability and hydrolytic stability allows oil to be reused

• Oil separates readily from water without loss of performance additive

5. Improved foam and air entrainment performance

• Prevents over flowing of reservoirs
• Eliminates “sponginess” from hydraulic systems and prevents pump cavitation


HYDREX AW hydraulic fluids are primarily recommended for heavy duty hydraulic systems that operate in industrial plants and outdoors in mobile equipment. HYDREX AW fluids may be used in systems equipped with fine filters down to 3 microns without loss of additives or causing filter plugging. Because of their wide applicability, long life, rust and foaming inhibiting features, HYDREX AW fluids may also be used to lubricate anti-friction bearings and gears found in circulation, splash, bath and ring-oiled systems. HYDREX AW fluids are approved against the following hydraulic equipment manufacturers’ specifications:

• Denison HF-0
• Eaton Vickers M-2950-S and I-286-S
• Cincinnati-Machine P-68 (AW 32), P-69 (AW 68) and P-70 (AW 46)
• Hagglunds AC-4.8
• Bosch-Rexroth
• Marlen Hydraulic Power Units (AW 68)

HYDREX AW fluids are recommended for use in equipment manufactured by Eaton Vickers, Hagglunds, Denison, Sauer-Danfoss, Bosch-Rexroth, Racine, Oilgear, Hydreco, Dynex and others. HYDREX AW 46 is recommended for use in the following injection moulding equipment manufacturers: Husky, Krauss-Maffei, Battenfeld, Demag, Soplar, Engel, and Nestal. HYDREX AW 32, 46, and 68 are GMLS2 approved, and are classifed as CFIA Type N2. HYDREX 22, 32, 46, 68, and 100 are classifed as NSF International H2. HYDREX is suitable for use where the following specifications are required:

• DIN 51524 Part 1 HL (AW 22)
• DIN 51524 Part 2 HLP (AW 32, 46, 68, 80, and 100)
• ISO 6743/4 Type HM
