Quick-Release Connector Kit

The Alphacool Eiszapfen HF kit provides two quick-release connectors with G1/4" inner threads on each side, built from brass with a Deep Black finish. They suit custom-loop builders who need to separate loop sections for maintenance, transport or component swaps without draining the entire system.

Sustained Flow Behaviour

The internal valve design keeps both halves sealed when disconnected and maintains a high flow rate when coupled, avoiding the restriction common in many quick-disconnect fittings. A double O-ring lock engages with an audible click, preserving seal integrity over repeated connect and disconnect cycles.

Thermal Noise and Power Impact

The connectors add no active components, so they generate no noise and draw no power; they simply become part of the loop's hydraulic path. Their compact 64.6 by 23.9 mm brass bodies introduce negligible thermal resistance, leaving coolant temperatures and pump workload unchanged in normal operation.

Questions about this item

Does the 64.6 mm length of these connectors restrict flow when the loop runs all day?

The design maintains high flow rates despite the 64.6 mm length, so continuous operation does not create a bottleneck.

Which fittings must I already have to install the G1/4" inner threads on this kit?

You need standard G1/4" male-threaded fittings or tubing adapters to screw into the inner threads on both sides.

Will the brass construction and double o-ring seal hold up if I reuse older nickel-plated blocks in the same loop?

Brass resists galvanic corrosion with nickel, and the double o-ring stays sealed through repeated quick-disconnect cycles.
