A “PC Male Thread Straight Fitting” is a type of connector commonly used in fluid and air transfer systems. It features male threading, designed to screw into a female-threaded component, creating a tight and secure connection that prevents leaks. The term “straight fitting” indicates that the fitting connects two parts in a linear manner, without changing the direction of the flow. These fittings are often made from durable materials like metal or plastic, allowing them to withstand various pressures and temperatures. The “PC” in the name could specify the fitting’s compatibility with certain types of tubing or pipes, or it might denote a particular design standard or material used in its manufacture.
