What is a Siamese connection used for?

A Siamese connection is a specialized fitting that allows two hose lines to be combined into one. This is particularly useful in firefighting operations where firefighters may need to increase the flow of water to tackle larger or more hazardous fires. By using a Siamese connection, two hoses can be attached at a single point to deliver a greater volume of water through a single discharge.

This fitting is particularly advantageous in scenarios where water pressure needs to be maximized, and it allows for flexibility in response strategies by making better use of available resources. Unlike other options, the Siamese connection does not serve to connect multiple nozzles, regulate flow, or split a hose into multiple lines, which emphasizes its unique role in fire suppression scenarios.
