Chrome Compression Fittings Sixpack

The Alphacool Eiszapfen sixpack supplies six chrome-plated brass compression fittings for custom liquid-cooling loops. Each fitting accepts hard tubing with a 13 mm inner diameter and 19 mm outer diameter and terminates in a standard G1/4 thread. The set targets builders who want a coordinated, high-flow connection kit with a durable metallic finish.

G1/4 Thread and Hard-Tube Limits

The G1/4 thread mates with 95 percent of water-blocks, radiators, reservoirs and pumps that use the same port standard. The compression design locks only to rigid tubing measuring exactly 13 mm ID and 19 mm OD; it cannot seal flexible hose or metric sizes outside that dimension. The slanted nut corners press the included O-ring firmly against the tube wall for a secure seat.

Six-Fitting Capacity and Headroom

Six straight sockets cover a typical CPU-plus-GPU loop with a single radiator and reservoir, leaving no spare fittings for extra blocks or a second radiator. Builds that add a motherboard VRM block, a second GPU or multiple radiators will exceed the pack quantity and require additional fittings. The chrome coating resists chipping so the finish remains intact through repeated assembly cycles.

Questions about this item

Should I choose these 19/13 mm fittings or a different size for my hard tubing?

Pick the 19/13 mm version only if your hard tubing has exactly 13 mm inner and 19 mm outer diameter; any other tube size needs a matching fitting.

How much flow restriction will these chrome fittings add to my loop?

The Eiszapfen series is designed for highflow performance, so the straight G1/4 sockets add minimal restriction while the slanted nuts keep the O-ring seal secure.

Will the G1/4 threads work with my existing water-blocks and radiators?

Yes, the ¼ thread is compatible with 95% of components, so these fittings will screw into almost any standard G1/4 port in your loop.
