Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Alphacool 17628 45 Degree Double Rotary Angled Adapter. Please read these instructions carefully before use to ensure optimal performance and longevity of your water cooling system components.
Product Overview
The Alphacool 17628 is a high-quality brass fitting designed for water cooling systems. It features a 45-degree double rotary design, allowing for flexible tubing routing in compact spaces. The adapter has G1/4" AG (male) to G1/4" IG (female) threads, suitable for 8/5 mm thick tubing. It is optimized for use in server and workstation systems where precise and reliable connections are crucial.

Safety Information
- Ensure all components are compatible before installation.
- Always turn off and unplug your computer system before installing or removing any water cooling components.
- Handle fittings with care to avoid damaging threads or O-rings.
- Perform a leak test on your water cooling loop before powering on your system.
Setup and Installation
- Preparation: Ensure your water cooling loop is drained and all components are clean.
- Thread Inspection: Carefully inspect the G1/4" threads on both the adapter and the component you intend to connect (e.g., radiator, pump, water block) for any damage or debris.
- O-Ring Check: Verify that the O-rings on the adapter are properly seated and free from damage. These are crucial for a watertight seal.
- Connection: Screw the G1/4" AG (male) end of the adapter into the corresponding G1/4" IG (female) port on your water cooling component. Hand-tighten until snug. Do not overtighten, as this can damage the threads or O-rings.
- Tubing Connection: If connecting tubing directly to the G1/4" IG (female) end of the adapter, ensure you use a compatible G1/4" male fitting for your tubing size (e.g., compression fitting for 8/5 mm tubing).
- Positioning: Utilize the double rotary feature to adjust the angle of the adapter to achieve the desired tubing path.
- Leak Test: After assembling your entire water cooling loop, perform a thorough leak test for at least 24 hours using a leak tester or by filling the loop with distilled water and running the pump without powering on other system components.

Operating Guidelines
Once installed and leak-tested, the adapter operates passively as part of your water cooling loop. No specific operational steps are required for the adapter itself beyond ensuring it remains securely connected and free from leaks.
- Coolant Compatibility: Use only clear and transparent water cooling liquids.
- Avoid Pastel Coolants: Particles and additives found in pastel or opaque coolants can clog and permanently damage water cooling components, including this adapter, radiators, pumps, and tubing. This can lead to system failure and may void the manufacturer's warranty.
Maintenance
Regular maintenance of your water cooling system helps ensure optimal performance and longevity of all components, including the Alphacool 45 Degree Double Rotary Angled Adapter.
- Coolant Replacement: Replace your water cooling liquid every 6-12 months, or as recommended by your coolant manufacturer.
- System Flush: When replacing coolant, it is recommended to flush the entire system with distilled water to remove any accumulated debris or old coolant residue.
- Inspection: Periodically inspect the adapter for any signs of wear, corrosion, or leaks, especially around the O-rings and rotary joints.
- Cleaning: If necessary, carefully clean the exterior of the adapter with a soft, damp cloth. Do not use harsh chemicals or abrasive materials.
