Castrol Alphasyn K 15, 20L

Castrol Alphasyn K 15 is a high-performance synthetic CLP (circulating and gear) and HLP (hydraulic) oil based on polyalphaolefins (PAO). It offers outstanding lubrication properties, oxidation resistance, and a wide operating temperature range, making it an ideal solution for demanding industrial applications.

Application:

Castrol Alphasyn K 15 is designed for use in central lubrication systems, spindle lubrication, industrial gearboxes, and hydraulic systems operating under high thermal stress. Its versatile formulation allows it to serve both as a circulation and gear oil as well as a high-performance hydraulic fluid.

Benefits:

• Standards compliance: DIN 51517 Part 3 (CLP), DIN 51524 Part 2 (HLP), ISO 6743/6-L-C, ISO 6743/4-L-HM.
• High wear protection: Brugger value > 61 N/mm², FZG scuffing test > 12.
• Excellent oxidation stability: ensures extended oil life and reduces sludge formation.
• Wide temperature operating range: thanks to high viscosity index (VI = 128) and pour point of -40°C.
• Thermal stability and low volatility: ideal for high-temperature conditions.
• Excellent air release and water separation: improves overall system performance.
• Seal compatibility: safe with conventional sealing materials.
• Free from heavy metals: environmentally friendly formulation.
