-
Prevention of Vapor Loss
A secure seal minimizes the escape of volatile hydrocarbons, preventing a reduction in fuel volume and a decline in octane rating. Evaporative losses not only decrease the amount of usable fuel but also contribute to air pollution. Inadequately sealed containers will exhibit a noticeable gasoline odor, indicative of ongoing vapor leakage. This loss directly undermines the fuel’s performance characteristics.
-
Inhibition of Contamination
Proper sealing prevents the ingress of contaminants such as water, dust, and debris, all of which can degrade fuel quality and damage fuel systems. Water contamination promotes corrosion and microbial growth, while particulate matter clogs fuel filters and injectors. A compromised seal allows these contaminants to enter, diminishing the fuel’s effectiveness. Examples include rust, which damages fuel systems and inhibits efficient combustion.
-
Maintenance of Vapor Pressure
A tight seal maintains the appropriate vapor pressure within the container, preventing excessive pressure buildup due to temperature fluctuations. Pressure relief valves on approved containers manage this pressure, but a compromised seal can render these valves ineffective. Without proper vapor pressure control, the container risks deformation or rupture, posing a significant safety hazard.
-
Mitigation of Oxidation
While not completely airtight, a properly sealed container minimizes the exposure of gasoline to oxygen, slowing the oxidation process that leads to gum and varnish formation. Oxidation degrades fuel quality over time, reducing its combustibility and leading to engine problems. Effective sealing, in conjunction with fuel stabilizers, provides a multi-layered defense against this degradation process.
In summary, proper container sealing is an indispensable component of long-term gasoline storage.
