FormulaMod GD-X 4-Pack G1/4" Rotary Fittings Black/Silver

Four-piece rotary fitting set

The FormulaMod GD-X pack contains four G1/4-inch rotary connectors machined from brass with a black and silver finish. Each fitting rotates freely so hard-tube runs can be aligned without stress on the tubing or the block ports. The quarter-turn design suits custom open-loop builds that need clean, adjustable routing.

G1/4 thread limits

The G1/4 BSPP thread is the de facto standard for consumer water-cooling components, but it caps the maximum bore at roughly six millimetres. Flow restriction rises sharply if you try to push larger tubing through the same port, so the interface itself sets a hard ceiling on loop throughput.

Replaces fixed-angle adapters

Swapping static 45-degree or 90-degree elbows for these revolvable fittings eliminates the trial-and-error of buying multiple fixed angles. The upgrade pays off when tube runs must change direction in tight spaces or when you plan to reconfigure the loop later without cutting new tube lengths.
