## Questions & Answers

**Q: Are the barbs removable?**
A: The hose fittings with the barbed end is made from aluminum tubing and is one piece. That tubing with the barbs on it is machine pressed into the aluminum water block. They cannot be removed although I imagine they can be grind off with a grinding tool.
