Eiszapfen inline filter for G1/4 loops

The Alphacool Eiszapfen filter is a clear POM plexi component with a stainless steel fibre microfilter. It threads into any G1/4 inch port and measures 20 by 25 millimetres. The unit ships new as part number 1012586 and includes one filter in the box. It is built for custom liquid cooling circuits that need debris protection without restricting coolant movement.

Suited for microstructure blocks and high-flow loops

Builders running dense microchannel water blocks benefit because the mesh stops particles that would otherwise clog narrow passages. The design delivers flow around fifty percent higher than an eight millimetre inner diameter tube and thirty percent higher than a ten millimetre tube, so restrictive blocks stay fed. Buyers who need a filter for larger debris or who cannot accommodate the 20 by 25 millimetre envelope should look elsewhere.

Stainless steel fibre microfilter

The filter media adds no measurable resistance until it reaches thirty to fifty percent clogging, making it the decisive specification for loops that prioritise pump headroom. Two G1/4 inch inner threads allow straightforward inline placement anywhere in the circuit. The clear POM plexi body lets you inspect contamination visually without disassembly.

Questions about this item

Should I pick the 20x25mm G1/4 filter or another size for my loop?

This model is a single 20x25mm inline filter with dual G1/4 inner threads. Choose it when your tubing and fittings use G1/4 threads and you need a compact filter that fits between standard water-block ports.

How much will the 50% higher flow claim actually help my pump and temperatures?

The stainless-steel microfilter flows roughly 50% better than an 8mm ID tube and 30% better than a 10mm ID tube. You will only see a measurable drop once the mesh reaches 30-50% blockage, keeping pump load low in normal use.

What does the G1/4 thread limit in terms of compatible fittings and tubing?

Both ends use G1/4 inner threads, so any standard G1/4 male fitting — rigid, soft-tube or compression — will connect directly. The thread itself does not restrict flow; the 25mm long filter body and microfilter mesh set the practical limit.
