Alphacool Eiszapfen 19/13mm G1/4 Compression Fitting Chrome Sixpack Brass (17241)

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.
