## Summary description

Compression-style fitting for PC liquid cooling from EK Water Blocks, model 3831109833346. Black finish, connecting thread 1/8" and outer diameter 23 mm. Supplied as a single piece per pack, suitable for connecting tubing in custom water-cooling loops, radiators and reservoirs where a 1/8" threaded port is required.

## Long description

EK-Quantum Torque Rotary STC-10/16 black compression fitting from EK Water Blocks is designed for soft-tube custom PC liquid cooling loops. This single-piece fitting accepts 10/16 mm (inner/outer) soft tubing and uses a compression-style locking ring to secure the tube on the barb. The fitting features a rotary joint on the threaded side for easier installation into a G1/4" port and a black finish with an interchangeable aesthetic color ring option (sold separately). Supplied individually, the fitting is intended for use where a 1/8" threaded connection is required and complements EK-Quantum series components.
Advantages
The rotary joint simplifies mounting by allowing the tube assembly to be tightened separately before installing the fitting into the threaded port, reducing stress on tubing. The compression locking ring compresses the tubing wall against the barb to prevent accidental pull-off, while exterior grooves improve manual grip during tightening. The fitting’s smooth, unbranded surface and optional aesthetic ring provide a low-profile industrial look that integrates well with other EK-Quantum products. Precision manufacturing and awarded design quality support reliable sealing and consistent fit in custom loops.

Key specifications

 Thread type: 1/8" thread for installation into corresponding ports
 Finish: black
 Outside diameter at body: 23 mm
 Compression-style locking ring for secure tube retention
 Rotary joint on threaded side to allow pre-assembly and easier alignment
 Supplied as a single fitting per pack
How to use
Slide the compression ring over the tubing, push the tubing fully onto the barb, and hand-tighten the locking ring until it compresses the tubing wall against the barb. Use the rotary function to align the fitting with the port before threading it into the G1/4" or compatible 1/8" port; this allows the tube assembly to remain fixed while the threaded side is rotated into place. For final tightening of the barb where required, use an 8 mm Allen key or compatible tool to avoid fingertip strain—apply moderate torque to avoid damage. Confirm all connections are seated and perform a leak test before powering the system.
Usage recommendations
Use only tubing materials compatible with the fitting (PVC, EPDM, Norprene, silicone, or other compatible flexible soft tubing). Do not overtighten the compression ring or apply excessive force with tools when engaging the barb’s hex pattern; this prevents damage to fittings and adjacent components. Consider adding an EK-Quantum aesthetic ring (sold separately) for visual customization and use an 8 mm Allen key or EK-Loop Multi Allen Key for safer installation.
