Alphacool MBVB085VK73RB Eiszapfen Quick Coupling Male Bulkhead G1/4 Inner Thread Deep Black Fitting

Deep Black G1/4 Bulkhead Quick Coupling

The Alphacool Eiszapfen male bulkhead fitting uses a G1/4 inner thread and NDSL technology to create a leak-free quick-release point in a custom water-cooling loop. Its deep black finish matches dark-themed builds while the brass construction resists corrosion. The coupling half connects to a matching counterpart for tool-free disconnection without draining the system.

Builders Adding Serviceable Disconnect Points

This fitting suits enthusiasts who want to separate components such as radiators or GPU blocks for maintenance or transport without spilling coolant. It is not for users who lack a compatible female quick-release half, because a single coupling cannot function alone. Buyers needing standard static compression fittings or larger thread sizes should look at other product lines.

Single G1/4 Port With High-Flow Path

The coupling handles the full flow rate of a typical G1/4 loop and remains drip-free when disconnected under pressure. It runs out of utility when a second coupling half is missing, when the bulkhead mounting hole is not available, or when the loop uses a thread standard other than G1/4.
