Quick Disconnect Kit for Water Cooling

This Alphacool Eiszapfen kit provides two G3/8" quick-release couplings for custom liquid-cooling loops. It suits builders who want to drain or rearrange components without emptying the entire system. The connectors are not intended for loops that must remain permanently sealed without any service access.

G3/8" Thread Limits and Adaptor Requirement

Each coupling carries a G3/8" thread on both sides, so standard 1/4" fittings cannot attach directly. An additional 3/8" to 1/4" adaptor is required for common tubing sizes. The design maintains high flow rates, yet the fixed thread pitch means compatibility depends entirely on matching G3/8" ports or using the correct reducer.

Brass Construction with N.D.S.L. Locking

Machined from brass with a Deep Black finish, each unit measures 88.5 x 28 mm. Pulling the outer ring disconnects the halves while both sides seal instantly to prevent coolant loss. Reconnection requires an audible click that engages a double O-ring, and the N.D.S.L. mechanism is built for repeated cycles without leakage.

Questions about this item

Should I choose the Deep Black finish for my loop?

Deep Black is the only finish offered for this 1012804 kit, so it matches any black-themed build without extra selection.

What does the 88.5 x 28 mm size mean once installed?

The connector pair adds 88.5 mm length and 28 mm diameter to the tubing run, fitting standard G3/8" ports while keeping a compact profile.

Does the G3/8" thread limit flow in practice?

The N.D.S.L. locking design maintains high flow through the G3/8" threads, and both halves seal instantly with a double O-ring when disconnected.
