- Does Envirosafe make refrigerant for R-134a systems?

- What is the difference between Proseal and the refrigerant two-packs?
- Proseal is a sealant treatment for R-1234YF systems, aimed at small leaks. The two-packs are 4oz cans of R-1234YF refrigerant for topping up a system.
- Where is Envirosafe cheapest?
- No live deals are listed on this page right now, so there is no current low price to point to. Compare the store prices shown for each product before buying.
- How much refrigerant does a 4oz two-pack add?
- A two-pack gives you two 4oz cans, 8oz total. That suits small top-ups; a system that is low enough to need more likely has a leak worth finding first.
- Can I buy R-1234YF refrigerant without a license?
- In the US, anyone can buy small cans of R-1234YF, but servicing a vehicle's AC system for others requires Section 609 certification. Follow the can and vehicle instructions for DIY use.
