• Supports efficient, lower-emission operation – a well-maintained, leak-tight system runs more efficiently, helping reduce running costs and refrigerant emissions when combined with good installation and maintenance practices.

Important: Errecom chemicals are trade products. Leak stops, oils and refrigerant-side additives should only be used by licensed refrigeration and air conditioning technicians following the Australia & New Zealand Refrigerant Handling Code of Practice and relevant AS/NZS standards.

What you’ll find in the Errecom range at HVAC Shop

1. Leak sealants & micro-leak products

For systems where you’ve confirmed a micro-leak and a physical repair is difficult or impractical, Errecom leak stops can be one of the tools in your kit – always alongside proper diagnostics and code-compliant repair practices.

• Errecom TR1163.AL.H3.S2 Extreme Ultra (6 mL leak stop)
  Polymer-free micro-leak sealer for HVAC/R systems that is formulated to help permanently seal tiny leaks in metal and rubber components without reacting with moisture or oxygen, and without clogging TXVs or capillaries when used correctly. Ideal for packaged units, splits and small commercial refrigeration once you’ve verified leak size and repaired what you reasonably can.
• Errecom TR1062.C.M2 Extreme Leak Stop
  A versatile leak stop designed to address small refrigerant leaks in AC/R systems, including automotive applications, where the active ingredients are triggered at the leak site to build a flexible seal.
• Hydrocarbon- and R600/R290-specific leak stops (such as Errecom Hydrocarbon / Extreme White options) for low-GWP cabinets and small refrigeration – always follow the TDS and local flammable-refrigerant guidance.

For testing and confirming leaks before and after using a sealant, pair Errecom leak stops with our leak detector tools in the Test & Measurements – Leak Detectors collection.

2. UV dyes & leak detection support

Finding the leak properly is still the priority. Errecom UV dyes and torches are designed to make trace leaks easier to spot:

• Errecom TR1068.E.H3 Brilliant Fluorescent UV Dye 60 mL – high-visibility fluorescent dye that circulates with oil and refrigerant, helping you visually confirm leak areas under UV light.
• Errecom RK1267 Flexible Bright Torch – a flexible UV inspection torch for tight plantroom corners and under-dash automotive jobs.

For A2L refrigerants like R32, always ensure your leak detectors and UV additives are rated and used in line with flammable-gas safety guidance.

3. Compressor oils & vacuum pump oils

Correct oil selection is critical for system reliability and warranty:

• Errecom Vacuum Pump Oil ISO 68 (1 L & 5 L) – formulated to handle deep vacuums and moisture without breaking down, supporting better evacuation and pump life.
• Errecom OL6015 POE 46 Lubricant Oil (5 L) – high-quality synthetic POE oil with excellent miscibility for HFC, HFO and many hydrocarbon systems, engineered to give stable lubrication, low foaming and good thermal stability.

You can also explore our broader Vacuum Oils collection and Vacuum Pumps to build a complete evacuation setup.

4. Easy-Inject tools & additives

For techs who regularly inject oils, leak stops, anti-acid additives or UV dyes:

• Errecom IN1031.R1 Easy-Inject 5/16" SAE (Injector Only)
  A reusable injector body that lets you add Errecom additives cleanly and quickly into AC/R systems without mixing or decanting – ideal for residential, commercial and automotive service work.

Pair Easy-Inject tools with the correct Errecom additive for the job (leak stop, UV dye, system flush, anti-acid) and always follow the manufacturer’s TDS and Australian standards.

5. Cleaning, drainage & system care chemicals

• Errecom Drizzle Drain Tube Cleaner (AB1078.K.01)
  Removes scale, organic residues, mould and algae in condensate drains and helps prevent new blockages, while being non-corrosive to metals.
• Errecom ER-RK1349 Acid Test
  A convenient test kit that helps you detect acid levels in compressor oils early, before corrosion or costly failures occur.

For coil cleaning, bagging and full system hygiene, see our Cleaning Chemical collection and Air Conditioner Cleaning Kits.

Compliance, safety & best practice in Australia

Using Errecom products correctly means staying aligned with Australian legislation and codes:

• The Australia & New Zealand Refrigerant Handling Code of Practice sets requirements for leak-tight systems, evacuation, charging, leak testing and maintenance.
• Guidance from the Australian Refrigeration Council (Look for the Tick program) makes it clear that if a leak exists, affected parts must be repaired or replaced before the system is refilled with refrigerant – topping up without repair is not allowed.
• For flammable and A2L refrigerants like R32, technicians must follow specific safety practices around concentration limits, ignition sources, evacuation and tool selection.

Errecom’s Extreme Ultra leak stops and UV dyes should therefore be used only by licensed technicians as part of a structured process:

1. Diagnose and locate the leak using rated leak detection tools and/or UV dyes.
2. Repair or replace accessible faulty components in line with the code of practice.
3. Where a confirmed micro-leak remains in inaccessible sections and the manufacturer allows, use Errecom leak stop as per the TDS.
4. Perform appropriate pressure or vacuum tests and final leak checks before re-commissioning.

Done properly, this approach supports lower refrigerant emissions, better system efficiency and fewer call-backs, while helping you meet your environmental and legal obligations.

Errecom & Extreme Ultra – FAQs

Is Errecom Extreme Ultra a replacement for proper leak repair?

No. Australian regulations and codes of practice require that if a leak exists, affected parts are repaired or replaced before refilling with refrigerant. Leak stops like Errecom Extreme Ultra are a tool for dealing with confirmed micro-leaks that can’t reasonably be accessed or repaired, and should only be used by licensed technicians following manufacturer TDS and the Refrigerant Handling Code of Practice.

Can I use Errecom leak stops and dyes in R32 and other A2L systems?

Some Errecom products are compatible with a wide range of refrigerants, including R32 and certain HFO blends, when used as directed. However, R32 is an A2L flammable refrigerant, so you must use A2L-rated tools, observe concentration limits and follow ARC/AIRAH safety guidance. Always check the product TDS, the equipment manufacturer’s instructions and the Australia & New Zealand Refrigerant Handling Code of Practice before using any additive in A2L systems.

Who is allowed to inject Errecom additives into HVAC/R systems in Australia?

Only technicians holding a valid ARC Refrigerant Handling Licence and working under a business with a Refrigerant Trading Authorisation (RTA) are permitted to handle scheduled refrigerants and inject additives. Businesses must also maintain appropriate leak detectors, recovery units and vacuum pumps, and keep records as required under the Ozone Protection and Synthetic Greenhouse Gas Management framework.

Do Errecom products help improve system efficiency?

They can contribute to better operation when used correctly as part of a broader maintenance strategy. Keeping systems leak-tight, oils in good condition and drains and coils clean – with products such as Extreme Ultra, Errecom oils and drain cleaners – supports efficient operation, but must be combined with proper commissioning, controls and routine servicing.

I’m a facility manager – how should I choose between different Errecom products?

Start with your service contractor. They should assess the system type, refrigerant (including whether it is flammable), leak history and oil condition, then recommend the right Errecom product – for example Extreme Ultra for a confirmed micro-leak, POE 46 oil for a specific HFC/HFO chiller, or UV dye and a flexible UV torch for long-term leak monitoring. They will also ensure everything is used in line with Australian codes and manufacturer warranties.
