RC-Project proudly introduces the all-new Smart Fuel Bottle Caps, engineered for maximum safety, leak-free operation, and uncompromising reliability. Compatible with most nitro fuel bottles, they are an essential upgrade for all RC enthusiasts.
Thanks to their innovative design, the caps lock securely onto the bottle straw and can be inserted into the bottle itself, ensuring a perfectly tight seal. With broad compatibility for straws measuring 5.8 to 6.3 mm in inner diameter, they fit almost any fuel bottle on the market effortlessly.
Say goodbye to messy fuel spills, pit-side accidents, and misplaced caps: enjoy total order, cleanliness, and peace of mind.
Before refueling, the cap can be placed in the bottle’s designated holder (where available). Alternatively, it can be left free: it automatically returns to its original position and won’t interfere during refueling.
Available in 7 vibrant colors, these caps help you stand out at the pit while matching your style or your team’s colors, avoiding confusion and mix-ups. Compatible with fuel bottles from top brands including: Sworkz, Infinity, JConcepts, HB, Hudy, Kyosho, VP Pro, Mugen Seiki, Arromax, LRP, Muchmore, Robitronic, Assault RC, ProTek RC, Serpent, Corsatec, Ultimate Racing, J&T, and T-Work's.
Manufactured using precision injection molding, RC-Project caps guarantee strict dimensional tolerances and uniform material quality, performance levels that 3D-printed alternatives simply can’t match.
