This item is a compression fitting for use with water cooling products. The 1/4" British standard thread with rubber o-ring allows it to screw securely into water cooling components with a tight leak proof seal. The screw connection is designed for use with PVC tubing with an inside diameter of 3/8" and an outside diameter of 5/8".
The base has a rotary element that allows the tubing and compression connection to spin 360° so tubing bend pressure won't unscrew your fittings!
