High-End Hard-Tube Fitting

The Alphacool Eiszapfen 1012934 is a 13 mm hard-tube compression fitting with a 90° bend and rotatable G1/4 thread. It targets custom-loop builders who want a premium, leak-tight joint with a distinctive deep-black finish.

Secure Seal and Colour Durability

A special coating process binds the matte black surface firmly to the metal, preventing chipping or peeling over time. The union nut’s slanted corners press the O-ring tightly against the tube for a secure hold that resists vibration during transport.

Rotatable 90° Layout for Tight Routing

The G1/4 thread mates with 95 % of water-blocks, radiators and reservoirs, while the 90° angle lets tubing turn sharply without kinking. Rotatable threads allow final alignment after tightening, freeing the builder from exact port orientation.

Questions about this item

How do I install the 13mm hard-tube into the 90° rotatable G1/4 compression fitting without leaking?

Slide the union nut over the tube, push the tube fully into the fitting until it seats against the internal stop, then tighten the knurled nut by hand until the slanted corners compress the O-ring firmly; the rotatable thread lets you align the 90° bend before final tightening.

Will the deep black coating on the 1012934 fitting need any special care or replacement over time?

The coating is bound to the surface by a special procedure that resists chipping and peeling; no periodic re-coating is required, and the O-ring is the only consumable part if it ever degrades.

What is the first limitation I will hit when running this 90° rotatable fitting continuously in a high-flow loop?

The 90° bend itself creates the primary flow restriction; the rotatable G1/4 thread and 13mm bore are designed for high flow, so the bend geometry is the limiting factor under sustained use.
