Hose couplings are used to firmly and reliably connect hoses to various types of water and pressurized air outputs. They may be found in a variety of commercial, industrial, and household contexts. Solid (flour, sugar, etc.), liquid (including chemicals and hydraulic oils), or gaseous media can flow through them (including compressed air). Brass is most known for its corrosion resistance properties, which are ideal for long-term use.
A male adapter has the threading on the outside of the hose fitting, while the female adapter has the threading on the inside of the hose fittings.
