The Metal Swivel Elbow 12mm x 1/4" M is a durable fitting designed to connect two pipes or tubes at a 90-degree angle, typically used in pneumatic, hydraulic, or fluid systems. The 12mm end is meant for 12mm diameter tubing, while the 1/4" male thread (M) connects to female-threaded ports or components. The swivel feature allows the elbow to rotate, offering flexibility in installation and adjustment, especially in tight spaces. This fitting helps create efficient, leak-free connections while providing the ability to change the direction of flow or attachment without disassembling the system.
