The EK-Quantum Torque STC 10/13 fittings are premium soft-tube compression fittings designed for custom PC liquid-cooling systems using 10/13mm (3/8” ID, 1/2” OD) tubing. Part of EK’s Quantum Torque series, they feature a secure compression design that grips compatible soft tubing while providing a clean, professional appearance inside a custom water-cooled build. The fittings use the widely adopted G1/4” thread, allowing them to connect with compatible water blocks, radiators, reservoirs, pumps, and other liquid-cooling components. This convenient six-pack provides multiple matching fittings for building, expanding, or upgrading a custom cooling loop.

This EK-Quantum Torque STC 10/13 6-pack is brand new and an excellent choice for PC enthusiasts who want reliable connections and premium EK styling for a soft-tubing water-cooling setup. The six-piece set makes it especially convenient for new builds or loop upgrades using compatible 10/13mm tubing. Ships fast with FREE SHIPPING.
