Alphacool Cape Corp Coolplex Pro 25 LT Reservoir, 25mm Diameter, Plexiglas, G1/4 15719

The Alphacool Cape Corp Coolplex Pro 25 LT stands out in compact water cooling loops where space is at a premium. Its slim 25 mm diameter and short 100 mm total length make it one of the smallest reservoirs in the Coolplex Pro series, yet it still offers a practical 39 ml fill volume and two G1/4" ports for flexible integration. Unlike bulky tube reservoirs, this model is built from crystal-clear Plexiglas (PMMA), giving you a direct view of coolant level and condition without adding unnecessary weight or size. It is a straightforward, reliable choice for small form factor PCs, external cooling units, or any loop that needs a minimalist reservoir with proven Alphacool quality.

• Ultra-compact tube reservoir: 25 mm diameter, 100 mm total length, 80 mm tube length
• Transparent Plexiglas (PMMA) body for easy coolant monitoring
• Two G1/4" threads for flexible inlet and outlet configuration
• Includes two mounting brackets for secure installation in tight spaces
• Compatible with all standard G1/4" fittings

In daily use

The Coolplex Pro 25 LT is designed for loops where every millimeter counts. Its small footprint allows mounting directly to the case, radiator, or pump top using the included brackets. The dual G1/4" ports let you choose the best routing for your tubing, and the transparent PMMA body makes it easy to spot air bubbles or low coolant levels at a glance. Because it operates safely up to 60 °C and 0.8 bar, it handles typical water cooling conditions without issue. Whether you are building a mini-ITX system or adding a secondary reservoir to a larger loop, this unit delivers consistent performance without dominating your layout.
