The PHANTEKS soft-tube fitting is a flat, straight G1/4" screw connection, which has a compression fitting on its other side for tubing with 13/10 mm (OD/ID). The threading is sealed with a rubber ring and the tube side of the PHANTEKS fitting has a hexagonal profile, this allows you to tighten the connection perfectly with an 8 mm Allen key. 

The fitting of this connector is made out of nickel-plated brass, the black nut is made of aluminium. Thanks to the compression effect of the ring cap, the tubing is particularly secure on the Phanteks soft-tube fittings.
