Copper Elbows for R410A & CO2 – High Pressure HVAC Fittings

Built for high-pressure ACR work, these trade-grade copper elbows deliver reliable performance with R410A, R32 and subcritical CO₂. Ideal for split-system installs and repairs, they’re engineered for smooth directional flow, excellent thermal conductivity and corrosion resistance, so your jobs run faster with fewer comebacks. Too easy.

Key Features & Trade Benefits

• Pressure-ready build – Rated up to 700 psi to handle modern high-pressure refrigerants, keeping systems stable under load.
• ACR-grade copper – Clean, consistent sockets for strong braze joints and leak-free commissioning.
• Two bend options – 45° and 90° for smoother routing, lower pressure drop and tidier installs.
• Fast to braze – Uniform wall thickness and cups make wetting easy, saving minutes on every joint.
• AS/NZS use – Intended for use with AS/NZS 1571 refrigeration-grade copper tube for compliant pipework.
• Sizes techs need – 1/4", 3/8", 1/2", 5/8", 3/4", 7/8" to cover common suction/liquid lines.

Why This Product Matters

On a steamy Brisbane rooftop in 40-degree heat, a tech swapped a kinked bend for a 90° elbow, swept nitrogen and re-brazed. Pressurised to 600 psi, no bubbles, no dramas—and no callback. Fair dinkum, the right elbow protects capacity by reducing restrictions and keeps charge inside the pipe where it belongs.

Round out your pressure test and commissioning with quality gauges (see Refrigerant Gauges) to verify balanced, leak-free installs.

Pro Tip

Always sweep nitrogen while brazing to prevent scale, then pressure-test (e.g., 500–600 psi for R410A lines where appropriate) with a high-pressure nitrogen regulator. Protect nearby surfaces with heat-blocking gel so you’re not chasing scorch marks. No worries.

Compatibility & System Info

• Refrigerants: R32, R410A, R134a and subcritical CO₂ applications (verify system duty and temperature/pressure envelope).
• Copper Tube: Use with AS/NZS 1571 refrigeration-grade tube; clean and cap practice recommended.
• Join Type: Brazed (socket/sweat). Use appropriate silver-phos filler for copper-to-copper; use flux when joining copper to brass.

Local Site Conditions (AU)

From Sydney plant rooms to coastal installs in Brisbane, high humidity and salt air can be brutal. These elbows’ tight grain structure and clean sockets help you pull ripper joints that stand up to the climate.

FAQs

Q: Are these elbows suitable for high-pressure refrigerants?
Yes—built for modern high-pressure systems like R410A and compatible with subcritical CO₂. Always confirm design pressures before commissioning.

Q: Can I use them on R32 systems?
Absolutely. They pair with correctly sized AS/NZS 1571 copper tube and standard brazing practice.

Q: What filler should I use?
Use a suitable silver-phosphorus alloy for copper-to-copper. When joining to brass (e.g., valves), use silver alloy with compatible flux.

Q: How do I verify a leak-free joint?
Pressure-test with nitrogen using a high-pressure regulator, then confirm with Leak Detectors for speed and accuracy.
