G1/4 Valves
G1/4 valves for shutting off or draining part of a loop: Alphacool Eiszapfen and Alphacool 2-way ball valves, Barrow mini ball valves and inline valves (male to female and female to female), and Thermal Grizzly DeltaMate drain valve fittings. A valve at the lowest point of the loop makes draining a quick job. Check valves and pressure release valves are listed here too.
