Tax included. Shipping calculated at checkout.
Material

On the Fiat Ducato and similar panel vans and motorhomes, the Ad Blue tank is not locked. This means that anyone passing by can unscrew the cap and remove the liquid. It would be even worse if foreign substances got into the tank. The locking bolt is fitted behind the locked tank cap. This means that when the fuel filler cap is locked, the Ad Blue cap is also locked.

Our locking bar is suitable for all campervans and semi-integrated vehicles. Does not fit fully integrated motorhomes.

Variants:

  • Black powder-coated steel: 3mm solid steel approx. 125g.
  • Stainless steel: 3mm stainless steel sheet approx. 125g.

All models are also suitable for sloping Ad-Blue lids!

Securing the AdBlue tank on the Fiat Ducato & equivalent vehicles

On the Fiat Ducato and equivalent panel vans as well as many motorhomes, the AdBlue filler cap is not lockable. This means the cap can be opened easily from the outside.

This creates a risk of AdBlue being stolen or – in the worst case – foreign substances entering the tank. Even small amounts of contamination can cause serious damage to the exhaust aftertreatment system.

The AdBlue protection bracket prevents exactly this scenario. It is installed behind the lockable diesel filler cap. When the fuel cap is locked, the AdBlue cap is blocked at the same time.

The lock is discreet, sturdy and can be installed without modifying the vehicle.

Compatibility

Suitable for many vehicles based on:

  • Fiat Ducato (from model year 2006)
  • Peugeot Boxer

Suitable for panel vans and semi-integrated motorhomes.

Not suitable for fully integrated motorhomes, as the fuel cap and AdBlue filler are usually located differently.

FAQ

Why should the AdBlue tank be protected?

On many vehicles the AdBlue cap is not lockable. Without protection, the cap can be opened easily. Foreign substances in the tank can lead to expensive damage to the exhaust aftertreatment system.

How does the AdBlue protection bracket work?

The bracket is installed behind the lockable fuel cap. When the fuel cap is locked, the bracket blocks the AdBlue cap at the same time.

Does the protection also fit newer Ducato models?

Yes. All variants are designed to work even on vehicles with an angled AdBlue cap.

Is any modification to the vehicle required?

No. The protection bracket is installed without any permanent modifications to the vehicle.
