Bus Fuel Filler Caps

Fuel filler caps for buses – Safety and fuel protection

A robust fuel filler cap is the first line of defence against contaminants that could enter the tank and damage the sensitive injection system. In passenger transport, protecting property is equally important, which is why Peterbus.pl offers a wide range of caps that meet the highest standards of sealing and safety. Our products are designed for the most popular urban and touring bus brands, such as Solaris, MAN, Mercedes-Benz, Volvo, Scania and Setra.

Types of fuel filler caps in our range

We provide various solutions tailored to the operating requirements of vehicles:

• Lockable caps: Effective protection against fuel theft (anti-siphon) and access by unauthorised persons.

• Keyless caps (bayonet type): Quick and convenient to operate, with robust sealing and resistance to mechanical damage.

• Caps with a venting system: Specialised designs that prevent negative pressure from building up in the tank, ensuring smooth fuel pump operation.

• Strainers and anti-theft protection: Fuel filler inserts that prevent liquid from being siphoned out of the tank, fitted beneath the cap.

• Fuel filler cap seals: Replaceable rubber components that ensure complete sealing and prevent fuel from leaking onto the bodywork while driving.

Why choose a fully functional fuel cap from Peterbus.pl?

A leaking or damaged cap means not only a risk of leakage, but also the risk of water or dust being drawn into the fuel system, which significantly shortens filter life. By choosing our products, you gain:

1. Sealing guarantee: Our caps are made of materials resistant to diesel fuel and extreme temperatures, eliminating the risk of seal deterioration.

2. Versatility and proper fit: We offer caps with standard diameters (e.g. 60 mm and 80 mm) as well as models designed for specific bus models, guaranteeing a perfect fit with the filler thread or fastening point.

3. Choice between new and used: We stock factory-new caps supplied with a complete set of keys, as well as fully functional used fuel filler caps, which are an affordable alternative when completing fleet equipment.

4. Environmental safety: A properly closed filler prevents vapours and leaks, which is essential during roadside inspections and for protecting the environment.
