For as long as most HVAC technicians can remember, all manufacturers of HVAC equipment used the same refrigerant. Whether it was R-22 or R-410A, regardless of the HVAC brand, the refrigerant was constant. Over the years, HVAC refrigerants have changed, making systems more energy-efficient and less damaging to the environment. Refrigerant leaks contributed to the depletion of the Ozone layer surrounding and protecting our planet. HVAC refrigerants and similar chemicals have been regulated to enforce the use of products that cause less harm when entering the atmosphere.
Effective in 2025, all HVAC manufacturers must use refrigerant class, A2L, in all air conditioning or heat pump systems. Currently, several types of A2L-classified refrigerants are being prepared for the marketplace. The primary refrigerants are identified as R-32 and R-545B. HVAC technicians will have to deal with multiple A2L refrigerants as they install, service, and maintain a variety of ducted and ductless HVAC systems. In short, A2L HVAC refrigerants are considered a global necessity due to their lower environmental impact, compliance with regulations, improved safety profile, energy efficiency benefits, and their role in driving sustainability in the HVAC industry.
Although refrigerant choices may represent a learning curve and require additional training, it’s comforting to know that regardless of the A2L refrigerant blends, RectorSeal has a variety of products that perform flawlessly with any A2L refrigerant.
Let’s take a closer look at the products and associated benefits from RectorSeal that are ready now to work seamlessly with any A2L refrigerant.
- PRO-Fit Quick Connect: flame-free, push-to-connect fittings for connecting refrigerant lines are quick, easy to install, and available in all sizes and configurations.
- Flaretite: seals help prevent leaks caused by galling, vibration, pulsation & extreme temp changes, providing a perfect solution for leak-free connections in harsh environments.
- NoKink: a flexible refrigerant line connector that allows easier, kink-free connections between the refrigerant line and a wall-mounted ductless condenser featuring stainless steel internal piping and jacketing.
- Novent: requiring special tools to apply and remove, the code-compliant caps protect against illness and death resulting from the inhalation of refrigerant. Also, they protect HVAC technicians from liability and help guard against refrigerant theft.
- Acid-Away: provides a unique approach to help prevent compressor burnouts by effectively removing the acid buildup in Polyol Ester refrigeration oils.
- Thread sealants: #5, Tru-Blu, T+2 – provide added protection and lubrication to help seal threaded connections in HVAC systems against refrigerant leaks.
- AC Leak Freeze: revitalizes HVAC systems by permanently sealing small, hard-to-find micro refrigerant leaks, enhancing system performance and helping extend compressor life.
- Turbo-Kleen: a chemical cleaner for HVAC systems used to clean refrigeration line sets from oil, sludge, carbon, and other damaging deposits.
- Nokorode Regular Flux: a lead-free, all-purpose, soft soldering paste flux with a special oil base to protect solder joints against corrosive attack by cleaning and fluxing all at one time.
