Serpent 1435 AFL Fuel Tank Cap O-Ring Set for Cobra GT 3.1 GP  [SER1435]

Improved AFL Cap Sealing Solution

Serpent refined its AFL tank cap design by swapping the foam gasket for a robust rubber o-ring. This update improves sealing reliability and keeps the closure performing well through repeated cycles. The item is designed specifically for the Serpent Cobra GT 3.1 GP and makes a sensible replacement for long term durability.

Why Rubber Beats Foam

Rubber o-rings resist compression and do not deform as quickly as foam, so the orange o-ring sustains a tighter seal under load. That resilience reduces the chance of fuel seepage and cuts down on maintenance intervals.

All-in-One Replacement Set

The kit contains everything needed to replace the existing lid on your fuel tank, allowing for a straightforward swap. Fitting this cap helps keep your RC running reliably for both track days and casual play.
