DiversiTech Super Seal Advanced

Built for busy tradies, DiversiTech® Super Seal Advanced 2-in-1 eliminates moisture and seals small, hard-to-find leaks—so you can get systems back online without a pump down. Compressor-friendly, DRY R™ boosts drier efficiency and helps prevent waxing and acid formation. Perfect for microchannel, heat pump and geothermal systems. Too easy.

Key Features & Trade Benefits

• 2-in-1: seals + dries — DRY R™ knocks out moisture and enhances drier performance, helping keep acid at bay and oil clean.
• No pump down needed* — Injects into a fully charged system, saving time on every callout and reducing recovery steps.
• Wide compatibility — Works with all oils and refrigerants including R410A/R32 and subcritical CO applications.
• Compressor-friendly formulation — Flows with the refrigerant to target microleaks, helping protect capacity and efficiency.
• Three kit sizes — 947KIT (≤5 kW), 944KIT (5–17 kW), 948KIT (≥17 kW) so you match the dose and avoid over-treating.
• Fast install — Clear, low-viscosity liquid with hose/can format for quick injection and no dramas.

*Recommended only if the system isn’t losing more than ~15% of total charge over four weeks.

Why This Product Matters

Real-world: on a muggy Sydney split with a pesky microchannel evap leak, the tech injected Super Seal Advanced, ran the unit under load, then verified with an electronic sniffer. No bubbles, no call-back—and the client was stoked. When you’re up on a roof in 40-degree heat, shaving an hour by skipping pump down is a bloody good win.

Close the loop with commissioning tools from our Leak Detectors collection to confirm the fix and document the job for the file.

Pro Tip

Before injection, pull moisture level down with a warm, dry system and a fresh filter-drier. After running Super Seal Advanced, verify with gauges and a sniffer, then note charge loss trend. If loss exceeds the guideline, find/repair mechanically. She’ll be right when you treat the cause, not just the symptom.

Compatibility & System Info

• Refrigerants: R410A, R32, R134a and others; suitable for microchannel, heat pump and geothermal; also used in subcritical CO applications.
• Systems: DX A/C and refrigeration where charge loss is minor; not for catastrophic leaks.
• Dosage: Choose 947KIT (≤5 kW), 944KIT (5–17 kW), 948KIT (≥17 kW).

Local Site Conditions (AU)

From coastal Brisbane installs with salt air to dense urban plant rooms in Sydney, heat and humidity accelerate moisture and corrosion. This 2-in-1 helps recover performance fast so you can move on to the next job. Ripper.

FAQs

Q: Is it safe for microchannel coils?
Yes—suitable for microchannel systems. Always follow dosing by capacity and confirm with a leak detector.

Q: Will it fix a big leak?
No. It’s intended for minor losses (typically <~15% over four weeks). Larger leaks need mechanical repair.

Q: Which kit size do I pick?
Match to capacity: 947KIT (≤5 kW), 944KIT (5–17 kW), 948KIT (≥17 kW). When in doubt, size conservatively.

Q: What should I use to verify the repair?
Use an electronic sniffer from our Leak Detectors, and confirm system pressures with a quality gauge/manifold from Refrigerant Gauges.
