Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing minimizing air entrance for brake cooling. Can be also used with conventional steel discs and clutch systems actuators. Widely exceeds DOT 3, DOT 4 and DOT 5. 1 standards (except for DOT 5. 1 viscosity at 40C). PERFORMANCES
Motul RBF660 Racing Brake Fluid
- All types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid.
- Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing minimizing air entrance for brake cooling.
- Can be also used with conventional steel discs and clutch systems actuators.
- Widely exceeds DOT 3, DOT 4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40°C).
PERFORMANCES STANDARDS - FMVSS 116 DOT 4 / SAE J1703 Extreme thermal resistance and stability:
- MOTUL RBF 660 FACTORY LINE very high boiling point (328°C / 622°F) is superior to conventional brake fluids DOT 5.1 (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini), and therefore enables effective braking even in extreme conditions.
- Provides better aerodynamic performance by reducing air entrance for brake cooling on cars.
Efficient when rainy:
- MOTUL RBF 660 FACTORY LINE very high wet boiling point (204°C / 399°F) is superior to conventional brake fluids DOT 5.1 non-silicone base (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini), and therefore enables to keep efficient braking in wet conditions.
- Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get to “vapor lock” phenomena.
- The wet boiling point is measured by humidifying the product with 3% of water.
RECOMMENDATIONS
- Avoid mixing with polyglycol based brake fluids.
- Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
- Store brake fluid in its original container, tightly closed to prevent moisture absorption.
- Aggressive chemical product if contact with hands, paint or varnish.
- If skin contact, rinse thoroughly with water.
PROPERTIES
100% Synthetic fluid, polyglycol bases.

not bad
Color: 7-in-1 Gunmetal Grey, Size: Rechargeable Set
Works well so far after a few months. We bought the s3cura and it quit after a short time so we got this one and so far so good.

Effortless and Elegant Wine Opener!
Color: 7-in-1 Black, Size: Rechargeable Set
I absolutely love my CIRCLE JOY Rechargeable Wine Opener! From the moment I opened the box, I could tell it was well-made and stylish. The sleek design looks great on my kitchen counter, and it feels sturdy in my hand.
The performance is amazing — it removes corks quickly and smoothly with just the press of a button. No more struggling with manual corkscrews or broken corks! The built-in rechargeable battery lasts a long time, and the charging base keeps everything neat and organized.
It also comes with handy accessories like the foil cutter, which works perfectly every time. I’ve used it for several dinner parties, and my guests are always impressed by how effortless it is to open a bottle.
If you enjoy wine and want to make your experience easier and more elegant, this electric wine opener is a must-have. It’s functional, beautiful, and makes a perfect gift for any wine lover! 🍷

Fabulous Product!
Color: 7-in-1 Black, Size: Rechargeable Set
This wine opener is fabulous! Foil cutter is sharp and works well. Easily removes the cork, then releases the cork from the corkscrew with a touch of a button. Also seals the wine which I have stored on its side in my wine refrigerator without any leaks. Charges quickly and I have opened many bottles of wine without needing to recharge it. Have had this item for a few months and if it continues to work this well, I will be amazed and very satisfied. Very reasonably priced as compared with similar products that I considered. Most of the other products cost more and did not do all of the functions that the Circle Joy does.
