L-HM HPC 68 Hydraulic Oil | 18L

Sinopec L-HM HPC Antiwear Hydraulic Oil ISO VG 68 is a premium-quality antiwear hydraulic oil formulated from Group II hydroprocessed base oils with a multifunctional additive system, meeting the performance requirements of leading international hydraulic oil specifications. Specified for hydraulic systems operating under heavy loads, sustained high pressures or elevated ambient temperatures, the L-HM HPC 68 provides the thicker, more thermally stable oil film required to maintain reliable protection where lighter grades are not appropriate. Achieves FZG fail load stage 12, NAS 7 cleanliness or better from the container and a TOST oxidation life exceeding 5,000 hours. A technically equivalent alternative to premium ISO VG 68 hydraulic oils from major international lubricant manufacturers, available at a competitive price point with full UK technical support.

The 18L pail is suited to maintenance technicians and mobile operators requiring a manageable pack size for servicing individual machines or for use on site.

Key Features

• Oxidation stability and service life. Group II hydroprocessed base oils provide inherently superior oxidation resistance compared to Group I mineral oils, resisting varnish and sludge formation in systems operating at elevated temperatures and under sustained high loads.
• Antiwear protection. FZG fail load stage 12 and proven pump test performance protect pumps, valves and actuators against wear in heavy-load, high-pressure hydraulic circuits where the higher viscosity grade is required for adequate film thickness.
• System efficiency. Rapid water separation, fast air release and effective antifoam performance maintain stable hydraulic power transfer and protect against cavitation-induced wear in high-pressure, high-temperature circuits.
• System cleanliness. NAS 7 cleanliness or better at point of filling reduces solid contaminant ingression risk and extends filter service life in heavy industrial hydraulic systems.
• Filterability and hydrolytic stability. Good filterability and hydrolytic stability ensure consistent performance and prevent filter blockage across extended service intervals in heavy industrial applications.
• Seal and material compatibility. Compatible with common elastomeric seal materials and paints specified for use with mineral hydraulic oils, preventing leakage and extending seal service life in high-pressure hydraulic systems.

Applications

Sinopec L-HM HPC ISO VG 68 Antiwear Hydraulic Oil is recommended for heavy industrial hydraulic systems, large hydraulic presses, die casting machines, injection moulding equipment and mobile plant operating under sustained high loads or elevated ambient temperatures where ISO VG 68 is specified.
