Alphacool Eiszapfen PRO HardTube Fitting 16mm OD

These brass fittings connect 16mm outer-diameter hard tubes in custom liquid-cooling loops. The six-pack supplies enough joints for a typical CPU-and-GPU build. They suit acrylic, brass or glass tubing and are aimed at enthusiasts assembling rigid-tube systems.

Check tube material and thread compatibility

The fittings use a G1/4" thread, so every component in the loop must share that thread standard. They are not recommended for Bitspower brand tubing, so verify your tube make. Confirm the loop can accommodate the 26mm fitting diameter without clearance issues.

Brass construction with internal nylon inserts

The chrome-plated brass body resists corrosion while the nylon inserts reinforce the tube inner wall against deformation up to 60°C. A wide compression seal and O-ring grip the tube from inside and out, tested to withstand over 8kg of tensile force without slipping.

Questions about this item

Does the 6-pack include everything needed to install 16 mm hard tubes, or are extra seals required?

The pack contains six complete Eiszapfen PRO fittings with integrated nylon inserts, O-rings and compression seals for 16 mm OD hard tubes; no additional parts are needed.

Why choose the 16 mm OD chrome brass version over other sizes?

This version matches 16 mm outer-diameter acrylic, brass or glass tubing and uses a G1/4" thread, while the chrome-plated brass body provides a uniform finish for visible loop builds.

How does the 60 °C deformation limit affect real-world loop reliability?

The internal nylon inserts stabilise the tube so it cannot soften and slip at temperatures up to 60 °C, and Alphacool tested tensile hold beyond 8 kg to confirm the joint stays secure under load.
