Chrome Hard-Tube Fitting 13/19 mm

This G1/4 straight compression fitting joins 1/2" ID by 3/4" OD hard tubing in custom liquid-cooling loops. A slanted nut profile presses the included O-ring firmly against the tube for a secure seal that resists vibration during transport. The durable chrome coating is bonded by a special process that prevents chipping or peeling over time. Three coloured O-rings are supplied, with an optional UV-reactive variant available for lighting effects.

Suits single-loop builders wanting premium chrome

This single straight fitting only addresses one connection point; a complete loop requires multiple fittings in various angles. It accepts only 13 mm ID / 19 mm OD rigid tubing, so soft-tube or other diameter systems are not compatible. The G1/4 thread fits standard water-blocks and radiators, but proprietary thread components will not work. Buyers needing angled, rotary or bulkhead configurations must source additional parts separately.

13 mm ID 19 mm OD hard-tube compatibility

The fitting is manufactured exclusively for 1/2" inner diameter and 3/4" outer diameter rigid tubing, identified as the 13/19 mm size. Using any other tube dimensions will prevent a reliable seal and risks leaks. The G1/4 male thread connects to the vast majority of liquid-cooling components that share this standard pitch. Confirm your tubing specifications match these exact figures before purchase.
