12mm OD Hard Tubing
Hardline tubing is a fairly new alternative to classic soft tubing. Made of a hard acrylic, fiber, metal or plastic material, hardline tubing is a cleaner, more precise way of tubing your system. While using hardline tubing in your build presents new challenges, the results speak for themselves. Available in three main sizes (12mm, 13mm, 16mm) for different preferences and builds.
Please note: 12mm Hardline tubing cannot be used with standard compression or barb fittings and must be used with specialized 12mm hardline fittings.
