Fuel tank vent cap chain tethers secure the fuel cap to the tank, preventing loss or misplacement. They ensure the vent cap remains accessible while maintaining proper fuel system ventilation. These tethers are typically made of durable materials to withstand harsh conditions.

Fuel Tank Vent Cap Chain Tethers are typically made from stainless steel (Grade 304 or 316) for corrosion resistance. The chain size ranges from 3mm to 5mm in diameter, with a tensile strength of 300-500 lbs. The tether length varies between 6-12 inches. The material is non-buoyant and designed to withstand fuel exposure, including gasoline, diesel, and aviation fuels. Viscosity and buoyancy are not applicable as these are mechanical components. Fuel system compatibility ensures resistance to hydrocarbons and UV degradation.
