SUPER STARS ST-900A – CORDLESS POWER TOOL FOR EXPANDING COPPER PIPES (INCH VERSION)

Super Stars ST-900A is a modern cordless electric tool for expanding (flaring) copper pipes, intended for professional installers and servicers of air conditioners, refrigeration systems and heat pumps. Thanks to the electric drive, it allows for fast, accurate and uniform production of expanded pipe ends without laborious manual operation. It provides repeatable results, a smooth surface and a standard expansion angle of 45°, which allows for high-quality preparation of pipes for connection in refrigeration and air conditioning systems. The built-in 11.1 V Li-Ion battery ensures excellent mobility and allows work even in the field, without the need to connect to the power supply. With one full charge, it allows for approximately 135 cycles of expanding pipes with a diameter of 5/8”.

FAST, ACCURATE AND EASY PIPE EXPANSION

The electric drive enables the expansion process to be carried out automatically, which significantly reduces physical effort and assembly time compared to conventional hand tools. The tool provides a uniform 45° expansion angle and a smooth surface, which enables high-quality preparation of pipe connections. Precise operation reduces the possibility of pipe damage and ensures repeatable results in everyday assembly and service tasks. It is suitable for use in:

• Installation of split and multisplit air conditioners.
• Installation of VRF systems.
• Installation and servicing of heat pumps.
• Installation of cooling systems.
• Refrigeration equipment in catering and shops.
• Servicing of air conditioning and refrigeration equipment.
• Field installation work.

WIRELESS OPERATION AND POWERFUL LI-ION BATTERY

The built-in option of using an 11.1 V Li-Ion battery with a capacity of 2200 mAh allows complete freedom of movement when working. The tool is suitable for use in various locations, even where access to the electrical network is not possible. With one full charge, it allows for approximately 135 cycles of expanding pipes with a diameter of 5/8". The battery charging time is approximately 100 minutes.

ERGONOMIC DESIGN AND LED LIGHTING

The compact design, low weight and ergonomic shape allow for comfortable handling and easier work even during longer assembly tasks. The built-in LED lighting improves visibility of the work area and facilitates use in poorly lit areas, such as installation shafts, technical rooms and inside air conditioning units.

It is important to know

Before purchasing, it is most important to check whether you need the right lacing tool, not just a general air conditioning accessory. The dimensions of the pipes you will be working on must also match the range listed on the product.

• This is a dedicated lacing tool; do not attribute other service tasks to it without confirmed data.
• Battery operation means that you are not tied to a power cord when working, but the operating time on a single charge cannot be estimated from the data provided.

In practice

🔧 A job that requires pipe lacing

🟢 Very suitable - the tool is intended for lacing; before choosing, check that the tube dimensions fit the specified range.

🔌 Work without a permanent connection to the electrical network

🟢 Very convenient - battery operation allows you to work without a power cable. The operating time on a single charge cannot be estimated from the available data.

Answers to frequently asked questions

Is the tool suitable for all pipe dimensions?

Not necessarily. Before purchasing, compare the dimensions of the pipes you will be processing with the range listed on the product.

Does this tool state how long it will run on a single charge?

The operating time is not specified in the available data, so it cannot be reliably estimated.
