The radiator takes the credit and the pump takes the blame, but the joint is what decides whether a loop survives its second year. The Meridian Four is a set of four rotary fittings built for the joints that have to move before they can seal.\u003c\/p\u003e\n\u003cp\u003eEach piece uses the G1\/4 thread standard that every block, radiator and reservoir in a loop already speaks, with a rotatable collar so the fitting can be oriented after it is tightened rather than before. Five geometries cover the practical cases, GD-SK, GD-X, GD-90, GD-45 and GD-FT14, giving straight, offset and angled paths around memory, motherboard heatsinks and the awkward corner where a tube run has to change plane. Bodies are machined aluminium, finished in silver or black, with no RGB and no lighting hardware inside them to fail.\u003c\/p\u003e\n\u003cp\u003eA four-piece lot is the right quantity for a single build: enough to solve the two or three joints that always resist a clean tube path, with spares left for the revision that follows the first leak test. Nothing here is decorative. The fittings hold torque, they do not introduce a second leak path into a loop that already has enough, and they can be repositioned during a rebuild without being replaced.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eA loop leaks at its joints, or it does not leak at all.

It Belongs\u003c\/h3\u003e\n\u003cp\u003eThe Meridian Four is for the builder assembling a custom loop in a mid-tower case, where the two hardest joints are always the same: the run from the CPU block over the memory towards the top radiator, and the return from the front radiator to the pump reservoir. It suits a first hardline build that needs angled adapters to keep tube bends clean, a maintenance rebuild that has to add a drain port, and a loop that has been moved between cases twice and needs the fittings to come apart and go back together without losing their seal.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-faq\" style=\"margin-top:30px;\"\u003e\n\u003ch3 style=\"margin:0 0 14px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom:18px;\"\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eQ: Do these fit any G1\/4 component?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;color:#4b5563;\"\u003eYes. G1\/4 is the standard thread used by the overwhelming majority of water cooling blocks, radiators, pumps, reservoirs and fittings, so these units thread into the ports those components already provide.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:18px;\"\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eQ: What is the difference between the five models?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;color:#4b5563;\"\u003eGD-SK and GD-X are straight and extended straight adapters, GD-90 and GD-45 are angled adapters, and GD-FT14 is a filter or pass-through style fitting. The choice depends on the angle a tube run needs to take at a given port, not on performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:18px;\"\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eQ: Are these brass or aluminium?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;color:#4b5563;\"\u003eThe bodies are machined aluminium.
