Features & Benefits

Sinopec TO-4 30 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.

    So excited for results, feels like it’s working!
    Size: Medium, Unit Count: 4
    First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

    Actually, better than I expected!
    Size: Medium, Unit Count: 4
    These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

    So so...
    Size: Medium, Unit Count: 2
    They do what they advertised. You can NOT walk in them you will stretch them and pop a hole in them. You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

    Great for dry feet or to help lock in moisturizer or medication
    Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
    They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.
