Alphacool Eiszapfen 19/13mm 90° Rotatable Compression Fitting Chrome 17243

Precision 90° Rotatable Fitting

The Alphacool Eiszapfen 17243 is a 90-degree rotatable compression fitting designed for custom liquid-cooling loops. It connects hard tubing with a 13 mm inner diameter and 19 mm outer diameter to any component with a standard G1/4 thread. The chrome-plated brass body resists chipping and peeling through a specialised surface treatment. Builders seeking a secure, high-flow corner connection in a premium finish will use this part.

G1/4 Thread Compatibility Limits

The fitting mounts into any port cut to the G1/4 parallel thread standard, which covers roughly 95 percent of water blocks, radiators, pumps and reservoirs on the market. It cannot be used with NPT, BSPT or proprietary thread patterns without an adapter. The 90-degree bend radius is fixed, so tight clearances around motherboard heatsinks or bulky GPU backplates may prevent installation. Tubing must be cut square and deburred for the internal O-ring to seal reliably.

Upgrading from Standard Elbows

This fitting replaces basic fixed-angle elbows or low-cost compression joints that can leak under vibration or transport shock. The rotatable collar lets you align the tubing run after the base is torqued down, eliminating stress on the hard tube. The multi-colour O-ring set included in the package adds UV-reactive accent options without buying separate rings. The jump is worth it when loop aesthetics, long-term seal integrity and service access matter more than the lowest component cost.
