Description

Who it’s for: Licensed HVAC/R techs and plumbers who want a fair dinkum 1/2″ expander head for the Imperial 175EX XpandR™ tool. Create uniform, leak-free sockets without extra fittings — quicker brazes, no dramas, and fewer call-backs.

Function & benefits

This 1/2″ replacement head (MPN: 175EX08) drops onto your 175EX to expand tube ends for brazing or soldering — cutting out couplings, speeding installs, and keeping pressure drops down.

  • Self-centring, hardened jaw segments — accurate, round sockets that braze cleanly and hold pressure.
  • Uniform capillary gap — better capillary action and joint quality; fewer “come back and fix it” jobs.
  • Reduced fittings & joints — save time on every run and carry fewer parts on the truck.
  • Built for site work — high-alloy, long-life segments that cop daily use, too easy.

Where it can be used

Made for HVAC/R and plumbing swaging on 1/2″ tube:

  • Soft copper straight from the coil (or anneal the end of hard-drawn copper before expanding).
  • Soft thin-wall steel & stainless within Imperial’s application limits (check wall thickness and job spec).
  • ✅ Ideal for refrigeration, air conditioning, and general plumbing where you want strong, leak-free brazed joints.

Pro Tip

Deburr the I.D., lightly chamfer the O.D., and wipe clean. If the line is hard-drawn, torch-anneal just the last 25–40 mm to a dull red and let it cool before expanding. You’ll get a smoother socket, tighter capillary, and prettier fillets.

Why this head matters

On a Gold Coast split change-out, we swapped a coupling for a quick expand on 1/2″ suction. Two heats, rod flowed like butter, and pressures were spot-on — job signed off before smoko. It’s a small upgrade that makes a bloody good difference across the week.

FAQs

Does this head fit the 175EX kit I already have?
Yes — it’s the OEM 1/2″ head for the 175EX XpandR™.
Can I expand hard-drawn copper?
Yes, but anneal the tube end first so it swages smoothly and stays round.
Is stainless OK?
Only soft, thin-wall stainless within Imperial’s application limits. Check wall thickness and follow site spec.
What else should I grab?
Keep sizes on hand and a deburr tool. If you need the full swaging set, the 175EX kit is the go.
