Features & Benefits

Sinopec TO-4 50 Heavy Duty Transmission Fluid is suitable for use in:

  • Heavy-duty transmissions, gearboxes, final drives and hydraulic systems used in off-highway applications, where a Caterpillar TO-4 product is recommended.
  • Other heavy-duty applications in the mining, construction, quarrying and agricultural industries.
  • Manual, power-shift and automatic transmissions where Allison C-4 fluids are recommended.
  • Mobile hydraulic equipment applications.
  • Applications where paper and elastomer disc materials are used, and advanced frictional properties are required to extend clutch life and provide slippage control under severe high-load conditions.

Features & Benefits

  • Excellent anti-wear properties and load carrying ability reduce gear wear and extend the life of heavy-duty transmission systems, gearboxes and final drives, leading to increased productivity and reduced equipment downtime.
  • Outstanding oxidation stability, thermal stability and detergency prevent the build up of deposits and ensure long fluid life.
  • Advanced frictional properties provide the clutch-friction retention and slippage control required in equipment that uses modern paper or elastomer disc materials.
  • Compatible with modern clutch materials and elastomers, to extend component life and prevent oil leakage.
  • Effective control of foaming together with good air-release properties ensure smooth transfer of power and shifting performance, and reduce fluid loss in severe service conditions.
  • Very good low-temperature properties protect against wear under cold start up and running conditions.

    Not bulky fit
    Size: Large, Color: (009) Gray Dawn / White / Prime Pink
    Thinner than UA other cushioning run socks, but this fit is perfect and doesn't shift in my shoe. I wear a women's 9.5 and determined Large doesn't squeeze my foot like Medium size (too exact). Bonus... avaliable olors beyond black and Grey.

    Love these socks!
    The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

    I stay on your foot they don’t slip in your shoe
    Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
    This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit
