Trade-grade R290 (Propane) in a compact 370 g bottle for service work on systems designed and clearly labelled for hydrocarbons. Perfect for licensed techs working on reach-ins, display cases and modern HC appliances. It’s bottle-grade, AHRI 700-compliant, and fair dinkum reliable—so your charge by grams is bang-on and call-backs drop.

Key Features & Trade Benefits

• AHRI 700 purity (≥99.5%) — consistent quality that helps prevent moisture/contaminant-related faults and repeat visits.
• Bottle-grade propane (C3H8) — non-odorised, colourless R290 formulated for refrigeration use (don’t use BBQ LPG).
• Low GWP, zero ODP — supports natural-refrigerant jobs and sustainability specs without compromising performance.
• Trade-sized 370 g can — ideal for precise gram-charges with a scale when servicing small charges.
• Clear compliance IDs — UN1978, CAS 74-98-6 noted on pack for transport/site paperwork.
• A3 flammable — for systems designed for R290 only; follow AS/NZS 5149 and ignition-control procedures.

Why This Product Matters

On a sticky arvo in Brissy, a tech’s chasing poor pull-down on a merch fridge. After leak-fix and pressure test, they weigh in a small R290 charge. With bottle-grade 99.5% purity and a decent scale, temps stabilise and the shop owner’s grinning. That’s the difference between “she’ll be right” and a ripper job that sticks. For more charging gear, see our Refrigerant Scales collection.

Pro Tip

Always charge by weight into evacuated systems, and leak-test with a HC-capable detector before energising. Keep ignition sources away, ventilate, and use intrinsically safe tools where required. No shortcuts—your future self will thank you.

FAQs

Can I use this to retrofit an R134a or R410A system?

No. Use only in systems designed and labelled for R290. Retrofitting non-HC systems is unsafe and non-compliant.

Do I need special tools?

Yes. Use HC-rated recovery/charging gear, leak detection suitable for flammables, and charge by grams with a refrigerant scale. See our Refrigerant Scales.

Is this different from BBQ LPG?

Yes. This is bottle-grade propane for refrigeration with AHRI 700 purity; don’t substitute LPG.

Where can I read the Australian guidance?

The Australian Government provides refrigerant safety and environmental guidance for technicians. See Australian Government Refrigerants information.
