Water Cooling Fittings
You've assembled the key components of your custom loop. Now you need water cooling fittings that connect everything securely and keep coolant flowing exactly where it should. CORSAIR fittings are built to hold up under the demands of a high-performance custom liquid cooling build, whether you're running a soft tube loop or a rigid hardline setup.
Types of PC Water Cooling Fittings
You've assembled the key components of your custom loop. Now you need water cooling fittings that connect everything securely and keep coolant flowing exactly where it should. CORSAIR fittings are built to hold up under the demands of a high-performance custom liquid cooling build, whether you're running a soft tube loop or a rigid hardline setup. Choosing the right liquid cooling fittings starts with understanding what each type does:
- Compression fittings: Designed for a firm, secure connection around your tubing. They grip the tube tightly to prevent leaks and work well with both soft and rigid tubing depending on the variant.
- Barb fittings: A simpler, friction-based option that slides over soft tubing. These are reliable for straightforward loops and are often used by builders who prioritize ease of installation.
- Angled and rotary fittings: These let you redirect tubing at precise angles without bending or kinking it. Rotary fittings allow you to fine-tune the tubing direction after installation.
- Pass-through fittings: Used to route tubing through case panels or reservoirs, giving your loop a clean, organized appearance.
- Adapters and extenders: These connect components with different thread sizes or port orientations, giving you flexibility when routing your loop through tight or complex case layouts.
Soft Tube vs. Hardline Builds
Soft tube loops are more forgiving and a solid starting point for builders new to custom liquid cooling. Barb and soft-tube compression fittings work well here. Hardline builds use rigid acrylic or PETG tubing for a clean, precise look, and they require compression fittings rated specifically for hard tubing. Make sure the fittings you choose match your tubing outer diameter before you buy.
Thread Standards and Compatibility
Most water cooling fittings use G1/4 inch threading, which is the standard across the majority of water cooling components including radiators, pumps, reservoirs, and water blocks. Always verify thread compatibility before mixing fittings from different parts of your loop.
Finishing Your Build
Fittings also contribute to the visual side of your build. Matching finishes across your loop — whether chrome, matte black, or another option — keeps everything looking deliberate and cohesive.
