ES D-Plug Resizable Fitting 31.5mm

This Alphacool ES D-Plug is a G1/4 male-to-male resizable fitting finished in Deep Black. It connects two female-threaded components in a custom liquid-cooling loop while allowing length adjustment for tidy tube routing. The fitting suits modders and enthusiasts building open-loop systems who need a compact, adjustable connector.

Adjustable Length 31.5mm

The defining specification is the 31.5mm resizable length, which lets you fine-tune the gap between blocks, radiators or reservoirs without cutting rigid tubing. This exact adjustment range decides whether the fitting can bridge your specific component spacing, so verify the required distance before purchase.

Deep Black Finish Only

The accessory bundle consists solely of the fitting itself in a Deep Black coating; no coolant, tools or additional seals are included. The colour matches other Alphacool ES-series parts for a uniform look, but buyers needing coolant or extra O-rings must source them separately.

Questions about this item

How much space does the 31.5mm length actually take up once the fitting is installed in a loop?

The fitting measures 31.5mm end to end so it adds that exact amount between the two components you are joining.

What does the G1/4 thread mean for compatibility with other parts in my build?

G1/4 is the standard thread used on most water-cooling blocks, radiators, reservoirs and pumps so the fitting screws straight into any port with that thread.

What clearance do I need around the fitting to tighten it by hand or with a tool?

The resizable design lets you rotate the body independently of the threads so you only need enough room to grip the fitting body after the threads are engaged.
