Meet the MalcoEdge TEMS Tubing Expander Multi-Size Kit — a hand-powered, field-ready solution for HVAC and refrigeration professionals who demand precise, leak-free copper and aluminum tube expansions without the hassle of couplings. This multi-size kit brings versatility and speed to every installation.

Nine color-coded expander heads are included, letting you quickly identify and match the exact tubing diameter in seconds. The result is faster setups, fewer sizing mistakes, and a cleaner, more professional finish on every job.

• Size-ready versatility: Expand copper and aluminum tubes across multiple diameters with nine heads—no adapters, no fittings, just reliable expansion.
• Precise, uniform expansion: Each head is engineered to produce smooth, consistent enlargements that align perfectly with the tube, delivering dependable, leak-resistant connections.
• Leak reduction by design: By removing the need for couplings and fittings, you minimize potential leak points and simplify field installs.
• Efficient in the field: A compact, manual tool that operates without electricity or compressed air, ideal for tight spaces and on-site work.
• Optimized for AC and refrigeration: Specifically suited for residential and commercial systems where clean tube ends and durable connections matter.

Ideal for technicians installing or repairing refrigeration loops, air conditioning lines, or any system using copper or aluminum tubing, the TEMS kit delivers consistent performance and confidence on every job. It’s a practical upgrade for service vans, workshops, and field crews aiming for faster, more reliable tubing expansions.

Tips for best results:

• Choose the correct color-coded head before starting to ensure a proper match with the tubing size.
• Inspect and deburr tube ends prior to expansion to promote a smooth finish and effective seals.
• Verify alignment after expansion and before final assembly to ensure a tight, leak-free connection.
