While the exterior grooves are designed for easy hand-tightening, the barb features an 8mm hex pattern. This allows you to use an Allen key for a more secure installation in tight spaces within your chassis.
Yes, these fittings support interchangeable aesthetic rings. You can purchase these rings separately to customize the look of your loop without needing to replace the entire fitting.
Yes, these fittings utilize the industry-standard G1/4 BSPP thread. They are fully compatible with all EK Water Blocks products and most other custom liquid cooling components on the market.
The fittings use a compression design where a locking ring tightens over the tubing wall. This creates a mechanical hold that prevents the tube from pulling off the barb during operation.
