Variable SLI/Crossfire Fitting

The Phobya 64280 is a G1/4 variable connector designed to link two graphics-card water blocks in a multi-GPU loop. It suits builders assembling custom liquid-cooling runs across cards from different vendors. The matte-black finish matches common water-block aesthetics.

Adjustable 12 mm Spacing

Its defining specification is the approximate 12 mm lengthwise adjustability that lets the fitting bridge mismatched port positions. This tolerance allows parallel or serial flow paths between blocks without forcing rigid alignment. The G1/4 thread ensures compatibility with standard water-cooling fittings.

Multi-GPU Loop Capacity

One fitting joins two blocks; additional units extend the chain to three or four cards for triple-SLI or quad-Crossfire topologies. The variable length absorbs manufacturing variance across brands, but the single-slot width limits use to boards with standard bracket spacing.

Questions about this item

How much spacing can the adjustable fitting cover between two water blocks?

The fitting telescopes by roughly 12 mm so it can bridge different card-slot gaps in a multi-GPU loop.

What thread standard does the connector use and what does that limit?

It uses a G1/4 thread, so it only mates with water blocks and fittings that share that same thread size.

How many expansion slots does the connector occupy inside the case?

It is a single-slot design, taking up just one rear bracket position per pair of cards.
