12mm OD Hard Tubing Fittings

Hardline Fittings cleanly and safely link hardline tubing to water cooling components and parts using a series of o-rings and compression collars. G1/4" threads make them easy to install into most water blocks, radiators and reservoirs. 12mm OD hardline fittings are the smallest hardline fittings we offer and can be used in conjunction with 12mm Hardline tubing for a clean, unique look.
