These components are essential connectors in a liquid cooling system for personal computers, establishing sealed pathways for coolant to circulate between the various elements like pumps, radiators, and blocks. They come in a variety of sizes and thread types, most commonly G1/4″, to ensure compatibility and a leak-proof seal. For example, a straight fitting might connect tubing directly to a radiator port, while a 90-degree rotary fitting could be used to navigate tight spaces within the PC case.
Their proper selection and implementation are critical for the effectiveness and reliability of the entire liquid cooling loop. Incorrect fittings can lead to leaks, reduced coolant flow, and ultimately, inadequate thermal dissipation, potentially damaging sensitive PC components. Historically, advancements in these connectors have mirrored the evolution of liquid cooling itself, with designs evolving to improve flow rates, ease of installation, and aesthetic appeal.
