Storz couplings are often used as fire hose couplings. However, they have wide usage in many industries, including refineries, agricultural, and construction use due to their resistance to corrosion, acids, and water. Storz couplings are non-shut-off symmetrical couplings and are also known as fire hose fittings. They can be connected by plugging the lug parts into each other and then twisting against each other. These couplings are ideal for working with water and other fluids, while users can also use them as connecting couplings for connecting other hose types.
