A cap becomes a vented jerrycan cap once a vent is added to it: usually a one-way valve is built into the cap. These valves and vents only let air pass in one direction and prevent liquids from flowing back or leaking.

Features of Vented Jerrycan Caps:
1- Protecting the contents of the jerrycan:
Leak resistance: Thanks to their special design, vented caps prevent liquids and gases from leaking, even when the jerrycan is moved or the pressure changes, so these jerrycans are fully liquid-tight and gas-tight.
Suitable for pressurized liquids: These caps are well suited to transporting liquids under pressure, because the valve regulates the pressure and prevents bursting or leakage.

2- Keeping out dust and contamination:
A vented cap keeps dust and contaminants out of the jerrycan, so its contents stay clean and safe.

3- Resistance to temperature changes:
These caps are usually resistant to temperature changes and perform well in different conditions, such as high or low temperatures.

4- High strength and long service life:
Vented caps are usually made of dense, tough plastic, which makes them highly resistant to pressure, impact and other damage. Sapel uses only new, high-grade raw materials for its caps and jerrycans, which is one of the reasons for the high quality of Sapel’s products.

5- Easy packaging and handling:
These caps are ideal wherever liquids need to be transported safely and conveniently. With a vented cap, liquids are protected from damage or spills during handling.

6- Quick opening and closing:
Many vented caps are designed to be opened and closed without special tools, which makes them easy to use and saves time.

Uses of Vented Caps:
Vented jerrycan caps are used on many types of jerrycans and liquid containers, especially for:
Storing and transporting chemical or industrial liquids: such as acids, paints, liquid fertilizers, solvents and other chemicals.
Water and beverages: for jerrycans in direct contact with food, a vented cap helps keep the contents safe and hygienic.
Liquids sensitive to temperature or pressure changes: such as industrial oils, fuels and other liquids that must be kept at a specific pressure or temperature.
