Fuel Tank Cap w/One-Way Vent Valve For Gas Gas EX 250 300 EC 350 F 2021-2026
Mud on your hands? Oily gloves? One twist -- and it's open.Born for extreme off-road riding.
This isn't a minor tweak to a traditional fuel cap -- it's a complete structural redesign built around the real-world pain points of extreme off-road environments.
From its gripping geometry to pressure regulation, from sealing performance to impact resistance, it delivers performance far beyond any OEM cap.
⚠ OEM Problems That Hold You Back
Flat outer profile makes it hard for your fingers to apply force
Smooth surface slips easily when wet, oily, or muddy
The result: hard to twist, easy to slip, prone to sticking and unreliable at critical moments.
Features:
-
A Full Upgrade -- Built for One-Twist Operation
Form = Function · Combat-Ready Grip Design
6-Flanged 3D Outer Ring
Gear-like contours create deep, defined grip channels. You can apply force from multiple angles without slipping -- even with muddy hands, oily gloves, or thick riding gloves. -
Central Integrated One-Way Venting System
Factory-molded, with a built-in automatic vent valve. It continuously balances internal and external tank pressure to prevent fuel spray caused by heat expansion or sudden impact. -
Reinforced Materials · Built for Harsh Terrain
CNC-Machined Aerospace-Grade Aluminum
Lightweight yet strong. Impact-resistant and corrosion-proof. Stays stable without deformation even after prolonged exposure to mud, water, sand, and high heat. -
Fluororubber O-Ring
Far superior to standard seals. Oil-resistant, heat-resistant, and anti-aging, maintaining exceptiling performance over long-term use -- no leaks, no worries. -
Can't Twist It? Slipping? Stuck? Solved at the Source.
A fully integrated optimization of structure + material + function, designed for the worst moments to use your hands:
Hands covered in fuel? Still non-slip.
Ice-cold muddy conditions? Still turns easily.
Desert heat? No fuel spray.
Hard impact or tip-over? No leakage. -
On Off-Road Terrain, It's Not a Part -- It's Confidence
The OEM cap is merely "usable." This one is truly "usable in the real world."
It lets you refuel quickly and safely in the harshest conditions -- no slipping, no sticking, no frustration.
A critical upgrade for any off-road machine.
Twist it open, and the journey begins.
Important Note:
For first-time installation, be sure to apply a thin layer of grease to ensure smooth snap-on operation and reliable sealing.
