What standard male hose thread size is typically used for outlets?

The standard male hose thread size typically used for outlets is 3/4 of an inch. This size is commonly found in garden hoses and hose bibs, making it the most widely used thread size for connections in residential outdoor water outlets. The 3/4 inch size strikes a balance between flow rate and compatibility with standard hoses, which is why it has become the industry standard.

Larger sizes, such as 1 inch or 1 and one-quarter inches, are less common for household applications and are more typically utilized in industrial or agricultural settings where higher water flow is required. The 1/2 inch size is also not standard for general household hose connections, as it would restrict water flow more than the standard 3/4 inch size. Thus, 3/4 of an inch emerges as the correct answer for standard male hose thread size used for outlets in residential contexts.
