Loop Splitter and Fill Port

The PrimoChill G 1/4in 4-Way Quad SX Adapter Block splits or combines a custom water-cooling loop at a 90 degree angle. It also creates an inline fill or drain access point for maintenance. The G 1/4in female threads accept standard fittings used by PC builders and modders. Four ports give flexibility for complex routing.

Thread Standard and Clearance

The G 1/4in thread is the de facto standard for desktop liquid cooling, so compatibility with common fittings is broad. Each port adds a connection point that must be sealed, so leak testing every joint is essential. The 23.9mm cube footprint fits tight spaces but leaves little room for large wrenches. Overtightening can damage the coated brass finish.

Four-Port Capacity Limits

Four ports handle a CPU block, GPU block, radiator and reservoir in a single junction. Adding more components requires another adapter or a distribution plate. The 90 degree layout restricts straight-through flow paths, so plan tube bends accordingly. Coated brass resists corrosion but candy SX finishes vary in tone between knurled and smooth surfaces.

Questions about this item

Should I choose the 4-way quad SX adapter or a simpler fitting for my loop?

Choose the 4-way quad SX adapter when you need to split or combine flow at a 90 degree angle or create an inline fill and drain point; a simpler fitting is sufficient for straight connections.

What does the 90 degree split mean once the block is installed in my loop?

The 90 degree split lets coolant turn a corner while dividing into three paths, so you can route tubing around tight spaces and feed multiple components from one junction.

Will the G 1/4in female thread limit flow or pressure in a high-performance loop?

The G 1/4in female thread is the standard water-cooling interface and does not cap flow or pressure in any practical loop; the 23.9mm cube body adds negligible restriction.
