FR-90 is an advanced penetrating oil that shocks rust down to -40°C, creating micro-cracks, allowing the lubricants to penetrate faster for rapid fastener removal. The silicone free formula is safe for use on all metal surfaces and most plastic, paint, and rubber coatings.
FR-90 can be used to release seized/rusted nuts and bolts, valves, heating pumps, immersion heaters, and fused parts.
