Fire-Resistant Hydraulic Fluids
Protect your people and facilities with effective fire-resistance
Choosing the right fire-resistant fluid can be a complex decision and involves balancing product performance, cost and regulatory requirements. Ongoing changes in industry standards can also influence the selection process.
Drive system efficiency in your hydraulic equipment with excellent component protection – all while reducing the risk of fluid ignition to improve the safety and productivity of your facilities.
Our range of fire-resistant hydraulic fluids provide enhanced protection to reduce the risk of ignition and prevent fire hazards in your operations.
Why should you use a fire-resistant lubricant?
Shell Fire-Resistant Hydraulic Fluids are specially formulated to avoid the propagation of a flame and are difficult to ignite – reducing potential fire hazards and improving safety.
With more compact hydraulic systems that operate at growing power and under increasing pressure, fire risks are becoming more prominent in industrial settings – despite advances in safety.
Hydraulic systems that operate in severe conditions, extreme temperatures or near an ignition source face an increased risk of fire. So, protecting your people, your equipment and your business from this is essential.
Reasons to use fire-resistant hydraulic fluids
Enhanced safety
Reduce the risks of even your most demanding applications with hydraulic fluids engineered to protect your people and assets from increased fire hazards.
Extended service life
Avoid the need for maintenance with high-performance fluids and oil monitoring services to improve your productivity and lower your total cost of ownership (TCO).
Wear protection
Reduce your maintenance costs with enhanced anti-wear properties that keep your equipment components and hydraulic fluid systems running smoothly for longer.
Operate in severe conditions
Operate productively and safely in extremely high or low temperatures, with consistent viscosity delivering responsive performance.
Reduce your impact on the environment
Mining or steel operations in environmentally sensitive settings need hydraulic fluids that not only deliver high levels of protection to equipment but also help you reduce the impact, of an accidental leak or spill, to the ecosystems around your facilities.
Our portfolio of specially formulated fire-resistant hydraulic fluids are difficult to ignite and designed not to propagate a flame from an ignition source, in comparison to mineral-based fluids.
It also features products that are classified as readily biodegradable with low eco-toxicity – engineered to reduce the impact of spills and leaks, helping you meet your environmental responsibilities.

Make a safe switch to fire-resistant hydraulic fluids
Switching from a mineral oil to a water-based or synthetic hydraulic fluid with fire-resistant properties is an effective way to improve the safety of your facilities. Using fire-resistant lubricants is a cost-effective option compared with installing mechanical fire-suppression equipment.
However, care must be taken to ensure the conversion is carried out correctly. It is important to review OEM requirements to confirm the compatibility of a lubricant with system components (including seals, hoses and filters). Even when using compatible lubricants, a small quantity of mineral oil can impair the fire resistance and stability of the new hydraulic fluid.
Similarly, when converting from one fire-resistant fluid category to another, the lubricants must not come into contact. Mixing incompatible lubricants can result in equipment failure. Even hydraulic fluids from the same category, but from different suppliers, should not be mixed unless you can clearly establish their compatibility. Be sure to consult with suppliers when looking to switch to an alternative hydraulic fluid.
