The
fuel tank cap also called the gas tank cap, and the filler neck and cap seal or
seal the fuel tank and prevent the fuel and impurities from evaporating. It
also protects the ignition safety, explosion and lightning protection, pump,
and ventilation. They are supplied with valves, flange sealing rings, and nuts.
The
raw materials commonly used in the production of tank caps are plastic, aluminum,
and stainless steel. In many cases, materials such as flour-based silicone
sealant and polyurethane are also used in the manufacture of the gas cap.
We
can find two types of fuel caps:
·
Vented tank caps
·
Non-vented fuel
tank caps
Vented
filler caps regulate fuel system pressure, especially for vehicles built after
1985. These fuel filler cap
have a special valve that can relieve this pressure if it is too high.
Non-vented
gas caps only regulate pressure, they don't relieve it.
Additionally,
standard fuel tank caps are essential to vehicle operation and safety. If you
took the cap off to refuel and forgot to put it on or forgot, you need to get a
new one as soon as possible. If your fuel caps look worn or cracked, it's
always a good idea to buy a new one and also consider lockout options.
Check
your car regularly; Along with everything else, consider replacing the gas cap.
You may not even notice anything unfavorable, but there may still be small
cracks or broken seals that could cause an engine fire.
