Tube Expanders

Explore our premium range of tube expanders for HVAC professionals. These tools precisely expand copper and aluminium tubing to create clean, consistent swages that accept mating tube for strong brazed or soldered joints—reducing extra fittings and keeping refrigerant flow smooth. Trusted brands include Imperial, Yellow Jacket and Mastercool.

Key Features & Benefits

• Fewer parts, stronger joints — expand tube ends for brazed/soldered connections, often eliminating couplings.
• Fast, accurate, repeatable — self-centring heads align and re-round tube for reliable results.
• Worksite-ready — kits cover common HVAC sizes with long-lever or hydraulic options.

Usage & Applications

Ideal for leak-tight brazed joints in refrigeration and air-conditioning installs, retrofits, and repairs. For best results: deburr cuts, use soft copper (or anneal hard copper), and allow capillary action during brazing.

Product Examples

• Imperial 175EX XpandR™ Swaging/Expanding Kit — precise swages with floating, self-centring head; heads from 3/8" to 7/8".
• Yellow Jacket 60407 Complete Expander Kit — long handles for leverage; multiple heads; re-rounds tube for clean, braze-ready fits.
• Mastercool Hydra-Swage 71600-A Hydraulic Expander — consistent, low-effort expansions on thicker wall or larger O.D. tubing.
