Decoration accessories Alphacool Apex Fillport chrome Brass 30mm 42mm 15mm

The Alphacool Apex Fillport is a compact chrome-plated brass fill port designed for easy filling of a custom water-cooling loop. Its flat, unobtrusive form blends with most PC cases and the included stop plug screws in nearly flush, giving a factory-installed appearance. The body and mounting nut are made from solid chrome-plated brass for durability and resistance to surface damage. To install, drill a 20 mm hole in the case and secure the fillport with the enclosed nut; position it at the highest point of the loop for correct operation. Compatible with G1/4" threaded connections. Dimensions: width 30 mm, depth 42 mm, height 15 mm.

Advantages

The chrome-plated brass construction ensures a sturdy, long-lasting fill port that resists scratches and chipping. Its low-profile design minimizes protrusion from the case, creating a neat, integrated appearance. The included stop plug closes almost flush, reducing visual disruption and helping maintain the overall case aesthetic. Simple installation with a 20 mm mounting hole and a standard G1/4" thread provides broad compatibility with common water-cooling components.

Suitable for

• Custom PC water-cooling loops requiring a discreet fill point
• Systems using G1/4" threaded fittings

How to use

Choose a mounting location at the highest point of the water-cooling loop inside the case. Drill a 20 mm diameter hole in the case panel or bracket. Insert the fillport from the outside and tighten the enclosed nut from the inside until the fillport is secure. Screw the included stop plug in when not filling; when filling, remove the plug, attach any required filling adapter to the G1/4" thread, and add coolant while monitoring levels. After filling, reinstall and tighten the stop plug to close the port.

Recommendations

Install the fillport at the highest accessible point of the loop to ensure complete filling and to avoid trapped air. Use appropriate G1/4" adapters or tubing during filling, and hand-tighten fittings to avoid damaging the chrome plating.
