Crater Fluids M & H
Industrial Open Gear, Chain & Wire Rope Lubricant

Crater® Fluids are black, adhesive, residual oil based lubricants recommended for a range of industrial applications where an easily applied, heavy lubricating oil is required.
Can include:
- Wire ropes
- Open gears (e.g., mining, quarrying, construction and dredging equipment)
- Chains and sprockets
- Flexible couplings
- Sliding surfaces (e.g., drag lines and shovels)
Suitable for application by brushing, swabbing, dipping, spraying, drip cup or spout type can. Spray application may be by conventional drum pump and spray nozzle equipment designed for fluid lubricants and greases.
Grade Selection
Selection of the appropriate grade depends on the severity of the application and the operating temperature.
Grade H has the higher film strength for severe-duty service or where operating temperatures are high.
Grade H has the higher film strength for severe-duty service or where operating temperatures are high.
- Protects metal surfaces
High load carrying capacity and adhesive properties of the residual base oil ensures that a tough, durable lubricating film is maintained on exposed gears and surfaces to protect against wear under adverse conditions.
- Tenacious lubricant coat
Protects exposed metal surfaces against the elements. The special compounding components provide additional rust protection by resisting water wash out.
- Quiet operation of gears
Highly cohesive lubricant coating remains pliable and effectively cushions gears and contacting surfaces.
- Easily and safely applied
Suitability for use with a wide range of refrigerants, helps minimise inventory and helps reduce the chance of misapplication.
Always confirm that the product selected is consistent with the original equipment manufacturer’s recommendation for the equipment operating conditions and customer’s maintenance practices
