Adjustable direct connection fitting for supported Koolance VID coolers in series or parallel. CNT-VDA2-BK is for SLI or CrossFire setups that span three card slots (one in between is bypassed). Koolance VID water blocks occupy the same slot as the video card. See this page for more details.

G 1/4 BSPP threading, made of brass with compression fittings and gaskets. Will work with any hose diameter going in and out of the Koolance video coolers. To adjust, loosen the threaded center nut, slide apart, and re-tighten. Do not adjust sliding fittings beyond the marked safety line.
