Short intro. If you’re cleaning old copper before a changeover or sorting a grotty retrofit, the Hilmor HLC007 Lineset Cleaner is a fair dinkum time-saver for HVAC techs. It blasts foam pigs down the run using nitrogen, clearing oil, sludge and swarf so you can commission with confidence and fewer call-backs. No mucking about—just fast, clean lines and a job well done.

Key Features & Trade Benefits

• Five nozzle sizes (3/8″–7/8″) – cover common HVAC/R lines without changing tools, ideal for split systems and light commercial. :contentReference[oaicite:1]{index=1}
• Foam pigs (reusable) – physically push out oil, debris and residue for a cleaner, drier line before evacuation and charge—bloody good for preventing contaminants getting to the compressor. :contentReference[oaicite:2]{index=2}
• Nitrogen-powered cleaning – uses compressed N₂ or inert gas, so there’s no moisture left behind; helps maintain system reliability. 
• Built for field use – rugged body and quick-connect nozzles; purpose-built for daily service work across resi and light commercial sites. 
• A2L-ready workflows – commonly used alongside A2L-compliant procedures when changing out R32 systems; keep oxygen out and lines 
• Carry case & full nozzle set – keep everything tidy in the van and on site—less hunting for bits, more time on the gauges.

Why This Product Matters

Real-world scenario: on a humid Brisbane arvo you’re swapping a tired R410A split to R32. You’ve recovered, brazed a join, and now you need the lines spotless before evacuation. With the HLC007 you fire a pig down from the outdoor to the indoor, catch it in a rag, then repeat. Quick purge, evacuation, charge—she’ll be right. Cleaner lines = fewer acids, fewer restrictions, and fewer warranty dramas down the track. For broader leak-test and purge gear, see our Nitrogen Regulators category. 

Pro Tip

Start at 30–40 psi and step up only as needed (tool rated to a max inlet of 60 psi). Always blow from outdoor to indoor where practical and use a rag or bottle trap at the exit to catch the pig—no mess on the client’s floor, no worries. 

Compatibility & System Info

• Line sizes: 3/8″, 1/2″, 5/8″, 3/4″, 7/8″ (five nozzles included). 
• Gas: Nitrogen or other inert gas (do not use compressed air). 
• Often used in workflows for R32, R410A, R134a changeovers/retrofits after recovery and before evacuation.
• Max inlet pressure: 60 psi (0.41 MPa); pressure inlet fitting: 1/4″ SAE male.

Safety note: Follow Aussie guidance around compressed gas handling and safe refrigerant practices. See Australian Government – Refrigerants.

FAQs

Q: Can I use this with A2L systems like R32?
Yes—use nitrogen for cleaning/purging and follow site safety guidance for A2L refrigerants. 

Q: Do I need a special regulator?
A quality nitrogen regulator makes life easier and safer. If you’re building a purge/pressure-test kit, our Regulators category has proven options for HVAC.

Q: How many foam pigs come in the kit and can I buy more?
You get two pigs per size. When you’re running low, grab Hilmor HLP012 replacements.

Q: What pressure should I use?
Start low (30–40 psi) and don’t exceed 60 psi to protect tubing and components.
