Barrow's Rigid tubing is a great alternative to classic soft tubing. Made of a hard acrylic material, hardline tubing is a cleaner, more precise way of tubing your system. You can bend or shape hard tubing using a bending cord, heat gun and bending tool. While using hardline tubing in your build presents new challenges, the results speak for themselves. Please note: 14mm Hardline tubing cannot be used with standard compression or barb fittings and must be used with specialized 14mm hardline fittings. Improper use can lead to cracking, leaks and damage to your system or components. Model: YK14-10
