DSZH Electric Copper Tube Expander for HVAC

Electric Copper Tube Expander for Precise HVAC Flaring

The DSZH Electric Copper Tube Expander is engineered for accurate, repeatable flaring of copper tubing in refrigeration and air conditioning systems. Designed for professional HVAC technicians, this cordless tool delivers consistent 45° flares across a range of common tube sizes, helping you achieve secure, leak-resistant joints on every installation and repair.

Powered by an 11.1V rechargeable battery (12V 2.0Ah pack, 2200mAh capacity), the expander offers reliable performance with up to approximately 135 expansions on 5/8" copper per full charge. The compact body (245 × 114 × 102 mm) and balanced weight distribution support comfortable one-handed operation, even in tight service spaces. Intuitive controls and clearly marked clamp heads allow fast setup and changeover between tube diameters.

Ideal for refrigeration maintenance, split-system air conditioners, and general HVAC service, this tool helps reduce manual effort while improving accuracy compared with traditional hand flaring. The consistent expansion profile supports better sealing surfaces, reducing the risk of leaks and repeat call-outs. Operating in ambient temperatures from 5°C to 40°C, it is well suited to typical workshop and on-site conditions.
