RC-Project is proud to present the brand-new smart caps for fuel bottles, designed to offer maximum safety, leak-free operation, and uncompromising reliability. Compatible with most nitro fuel bottles, they represent an essential upgrade for all RC racers.

Thanks to their innovative design, the caps lock securely onto the bottle tube and can be inserted into the bottle itself, thus guaranteeing perfect sealing. Thanks to their broad compatibility with tubes whose inner diameter is between 5.8 and 6.3 mm, they effortlessly fit almost all models available on the market.

Say goodbye to fuel spills, pit accidents and lost caps: enjoy complete order, impeccable cleanliness and peace of mind.

Before refueling, the cap can be placed in the dedicated holder on the bottle (if applicable). It can also be left free: it automatically returns to its original position and does not interfere during fueling.

Available in 7 vivid colors, these caps allow you to stand out in the pits while matching your style or your team's colors, thus avoiding any confusion or mixing. Compatible with fuel bottles from major brands, notably: 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, the RC-Project caps guarantee tight dimensional tolerances and uniform material quality, performance levels that 3D-printed alternatives simply cannot equal.
