Fitting kit Alphacool 17475 — brass fittings, black, Ø 22 mm, H 20 mm

Alphacool 17475 fitting kit is a set of brass fittings finished in black, designed for use in custom PC liquid cooling systems. With an outer diameter of 22 mm and a height of 20 mm, each fitting provides a compact, robust interface for tubing and cooling components. The kit is intended to deliver secure connections and reliable seals between radiators, water blocks, reservoirs and associated tubing in desktop water-cooling loops.

Advantages

The brass construction ensures mechanical strength and corrosion resistance suitable for long-term use in closed-loop cooling systems. The black finish offers visual consistency with dark-themed builds and helps reduce light reflections inside the loop. The compact 20 mm height and 22 mm outer diameter make these fittings compatible with tight mounting spaces while maintaining adequate sealing surface area. At approximately 23 grams per fitting, the components are lightweight without sacrificing durability.

Suitable for

• Custom desktop water-cooling loops
• Connecting radiators, water blocks and reservoirs
• Replacing or expanding existing fittings in PC cooling systems
• Systems where compact fittings are needed to fit constrained spaces

Key specifications

• Material: brass
• Finish: black
• Outer diameter: 22 mm
• Height: 20 mm
• Weight: 23 g (per fitting)

How to use

Install the fittings by first preparing the tubing and connection points: ensure surfaces are clean and free of debris, cut tubing squarely, and slide any required compression rings or seals into place. Hand-tighten the fitting until secure, then apply incremental turns with appropriate tools as needed to achieve a leak-free connection without over-torquing. After assembly, perform a pressure or leak test on the loop before powering the system to verify sealing integrity.

Recommendations

Use compatible tubing and sealing components sized for the 22 mm outer diameter and follow standard water-cooling assembly practice. Periodically inspect fittings for signs of wear or corrosion and re-check tightness after initial operation. Avoid aggressive chemicals that could degrade seals or finishes.
