Vented / Breather Screw Cap to Suit Poly Water and Diesel Tanks by Boab

This vented (breather) screw-on cap for a water or diesel tank is designed to screw onto the opening of your water or diesel storage tank. The cap has a screw thread on the inside, which is used to tighten the cap onto the tank, forming a secure seal.

The cap has a built-in vent, which allows air to enter the tank as liquid is dispensed, preventing vacuum pressure from building up and making it difficult to pour the liquid. It essentially allows the tank to breath while preventing spillage. The vented screw-on cap helps ensure that the water or diesel tank can be easily filled and emptied, while also helping to prevent spills and leaks.
