Summit R410A with seal is my only R410A cylinder on my truck, because if you have to charge a A/C unit, it has a leak.

Summit R410A with seal is our insurance against those costly and aggravating call backs.

Our company hates the small nuisance refrigerant leaks. We install Summit R-410 with sealer and dye in every new system. We realized the value in never hearing the call from our customer with a small leak that leaks one or two pounds per year.
Thanks Summit R-410 with sealer!

I just love this business!!
