Brass HardTube for custom loops

The Alphacool Brass HardTube 13mm OD 40cm Chrome is a rigid brass tube designed for custom liquid cooling loops. Its chrome-plated finish provides a reflective aesthetic for showcase builds. The tube suits enthusiasts assembling hard-line water cooling systems who want a metallic appearance.

Wall thickness and cutting preparation

A 0.8 mm wall thickness makes the tube strong while remaining workable with standard tubing tools. Cut ends must be deburred using fine sandpaper or a dedicated deburrer to protect fitting O-rings from damage. The durable chrome plating resists scratches and chipping under normal handling.

Single straight length and loop planning

Each piece measures 40 cm with a 13 mm outer diameter and 12.2 mm inner diameter, weighing 101 g. One tube covers a short straight run; complex loops need multiple lengths and separate fittings. Builders requiring longer continuous sections or pre-bent shapes must source additional parts.

Questions about this item

How often should the chrome plating on these 13 mm brass tubes be inspected for wear that could affect O-ring sealing?

The chrome plating is extremely durable; scratches or chipping only occur with strong force, so routine inspection intervals are not defined by the manufacturer.

What is the maximum continuous coolant temperature these 12.2 mm ID brass tubes can withstand before the chrome layer degrades?

No temperature limit for the chrome plating is specified; the brass tube itself handles typical water-cooling loop temperatures without issue.

How much heat does a 40 cm length of this 101 g brass tube add to the loop when the system runs all day?

The tube is a passive component; it does not generate heat and its thermal mass is negligible compared with active cooling parts.
