EK-RES X3 150 Lite is a cylindrical standalone reservoir, manufactured from premium quality 60mm acrylic tube and POM Acetal end caps in black color. The sealing is performed by quality EPDM rubber washers. EK-RES X3 150 Lite reservoir is primarily made to be paired with EK-XTOP Revo Dual D5 with an enclosed EK-AF Extender Revo Dual D5 Add on. This is a small adapter fitting extender that mounts the reservoir to the EK-XTOP Revo Dual D5 and is not sold separately. The top of the reservoir features three G1/4" threaded ports, while the bottom has one G1/4" threaded port. This allows the reservoir to be used as a standalone reservoir in various positions, such as horizontal and vertical configuration. The inner face of the top comes preinstalled with one Acrylic tube that serves as a suction point in the horizontal position. Additionally, enclosed PE foam can be used to diminish vortex occurrence. The unit comes with a pair of special holders that allow the reservoir to be installed directly on the computer chassis.
