When it comes to stopping coolant leaks, not all products are created equal. Rislone offers two powerful options: Liquid Aluminum and Liquid Copper. Each is engineered for different types of leaks and offers unique benefits for your vehicle's cooling system. Understanding the differences will help you choose the right product for your needs.
Rislone Liquid Aluminum
Key Features:
- Advanced Technology: Combines Liquid Aluminum™ to seal leaks and condition your system with Xtreme Cool™ to reduce coolant surface tension, enhancing heat transfer and helping prevent overheating.
- Versatile Leak Sealing: Safe and effective for plastic, aluminium, and metal (including copper/steel) radiators, heater cores, gaskets, and freeze plugs.
- Antifreeze Compatibility: Works with all types of antifreeze, including traditional green/blue and extended-life OAT/HOAT coolants—no draining or flushing required.
- Reliable Performance: Meets ASTM D6107 standards for stop leak additives.
- Routine Maintenance: Ideal for small to moderate leaks, quick sealing without clogging, and system conditioning to help prevent future leaks.
- Safe Formula: Uses fiber additives and wetting agents instead of sodium silicate (liquid glass) for effective sealing and cooling benefits.
Best Use: Small to moderate leaks, routine maintenance, and preventative system conditioning.

Rislone Liquid Copper
Key Features:
- Powerful Leak-Sealing Formula: Uses sodium silicate “liquid glass” with organic and synthetic fibers, copper, and minerals.
- Seals Larger Leaks: Designed for tougher leaks, including cracked blocks, cylinder heads, intake gaskets, heater cores, freeze plugs, and radiators.
- Heat-Activated Plug: Forms a composite plug as fibers lock together, and the sodium silicate hardens under heat to create a durable seal.
- Universal Compatibility: Safe for all types and colours of coolant.
- Severe Leak Solution: Recommended for leaks that other stop-leak products can’t handle.
Best Use: Large or stubborn leaks in critical engine components where a stronger, heat-activated seal is required.
Code: 41108
Choosing the Right Product
Liquid Aluminum is ideal for small to moderate leaks and routine maintenance. It helps prevent overheating, improves heat transfer, and conditions the system without risking clogging.
Liquid Copper is designed for larger or more severe leaks, including cylinder heads, blocks, and other critical engine components. Its heat-activated formula forms a strong, reinforced seal for reliable repair.
Quick Tips for Customers
- Liquid Aluminum does not use “liquid glass.” It relies on fibers and wetting agents to improve system performance.
- Liquid Copper includes sodium silicate for heat-activated sealing, reinforced with fibers and copper, making it suitable for severe leaks.
- No Draining Required: Both products are safe for all types of antifreeze, saving time and hassle during application.
Choosing the right Rislone product ensures your vehicle stays protected, your cooling system runs efficiently, and leaks are addressed effectively—whether it’s a minor drip or a major repair.
