Replaceable expander head by Super Stars. Compatible with both ST-100 manual expanders and ST-300 hydraulic expanders. Designed for use with soft copper tubes with a diameter of 3/8″, commonly used in refrigeration, air-conditioning and heat pump installations.

Made of a durable tool steel alloy, it enables precise socket forming for brazed connections. Expanding the end of the tube allows another tube section to be inserted and joined by brazing, without the need for a coupling. This reduces the number of brazed joints in the installation, shortens installation time and lowers material consumption.

Main features and benefits:

• 3/8″ size: compatible with ST-100 and ST-300 expanders.
• For soft copper tubes: ideal for refrigeration, air-conditioning and heat pump systems.
• Precise workmanship: even expansion and accurate joint fit.
• Durable construction: made of high-strength tool steel alloy.
• Fewer fittings required: eliminates the need for a coupling – less brazing and faster installation.
