ROMAX Compact III Insert TH16-20-26-32 set, 2Ah, EU, CAS 1000004425

Practical pipe‑crimping kit for harsh conditions

The ROTHENBERGER Compact III kit is a tool designed for installers who need fast, precise and reliable crimping of fittings in confined spaces. It runs on an 18 V battery, allowing unrestricted movement without cables – ideal for installation in walls, floors or behind services.

The cycle time for one crimp is only 3 seconds. This is not marketing – it is the result of efficient pressure build‑up in the electro‑hydraulic system, which operates without delay even during repeated cycles. No waiting, no strain – you work and move on.

The crimper handles metal pipes up to Ø 35 mm and plastic pipes up to Ø 40 mm. The kit includes three pairs of TH backings: 16 mm, 20 mm and 26 mm – a wide enough range to cover most typical heating and sanitary systems. No need to carry several tools – everything is in one unit.

The Li‑HD 2 Ah battery is not just a power source – it provides energy for a full working day. You do not have to interrupt the installation to recharge it. The charger is included, and the battery is compatible with the CAS system – so you can swap it for another one during work if you have a spare.

The total weight of the kit is 2.5 kg. That is little, not because it is light, but because the centre of gravity is perfectly balanced. Hand fatigue is minimal. The 34 cm length allows you to reach even hard‑to‑access places without over‑extending your arms.

It operates in temperatures from –10 °C to +60 °C. That means you can use it outdoors in winter, in an unheated cellar, or near radiators. There is no risk of damage from temperature or cold.

Everything fits into the ROCASE case – you won’t lose the backings or the battery. Assembly is simple: insert the backing, press the button and crimp. No settings, no calibration – just operation.

You do not need an app for basic installation – but if you want to collect data on performed connections (data logging), the ROTHENBERGER App allows real‑time recording of each cycle. This is useful for documentation or installation audits.
