Cooling system part Alphacool 17258

The Alphacool 17258 is a black cooling system part designed to improve routing and connection flexibility within liquid cooling loops. It incorporates a 1/4" connecting thread and a 90° angled body, allowing compact and space-saving installations in tight areas of a PC cooling system. With compact dimensions of 25 mm width, 18 mm depth and 25 mm height, the component integrates into radiators, reservoirs or tubing runs where precise orientation and reliable sealing are required.

Advantages

This 90° angled connector provides stable, leak-resistant connections suitable for liquid cooling circuits. The metal construction and black finish ensure durability and visual consistency with other cooling components. The 1/4" threaded interface supports standard fittings and enables straightforward assembly and disassembly during maintenance or system upgrades. Its small footprint helps reduce stress on tubing and prevents kinking in confined spaces.

Suitable for

• Custom PC liquid cooling loops that require angled connections
• Compact or small-form-factor builds with limited installation space
• Connections between radiators, reservoirs and pumps where orientation control is needed

Key specifications

• Connection thread: 1/4"
• Angle: 90°
• Material finish: black
• Dimensions (W×D×H): 25 mm × 18 mm × 25 mm
• Weight: 0.1 kg

How to use

Prepare the mating fitting and ensure threads and sealing surfaces are clean and free of debris. Apply appropriate sealing method if required by your system (for example, a suitable thread seal or gasket) and hand-start the 1/4" thread to avoid cross-threading. Tighten to the manufacturer-recommended torque or until secure; avoid excessive force that could damage the fitting or connected components. Orient the 90° elbow to align tubing or ports as needed and check for leaks after filling the loop and during initial operation.

Recommendations

Use the Alphacool black 90° connector in systems that use standard 1/4" fittings and compatible materials. Inspect seals and connections periodically and re-tighten only when the system is drained or pressure-relieved. Avoid mixing incompatible metals or incompatible coolant additives that could affect long-term reliability.
