Flex Inject Sealant Advanced, 3.75" x 9.75" x 1.5" (985)

what I wanted at a fair price and arrived on time!

I used this on Stoelting F231 froyo machine with a small leak where had to add 404 every month or so, 2 months and no issues so far!

Won’t know for sure for a few months how effective it works.

Product design facilitates the application of this product into the HVAC system experiencing leaks. Not having to attach additional hoses to install product is incredibly convenient. Once applied, unless the leaks exceed holes larger than 300 microns, this product will close them all, extending the life of the affected system, more importantly, for those systems still running R-22, it provides an ethical way of not having to charge the system to get by knowing that R-22 will continue escaping and affecting the environment.

I JUST PURCHASED THIS SEAALANT FROM PATRICK'S SUPPLY . I HAD ONLY ONE PINHOLE SO SMALL THAT IT WASS NOT VISIBLE TO THE EYE AND MY 12X POWER MAGNIFIER. ONLY WAY I FOUND LEAK WAS BY TOUCH . I DETECT LEAKS OF ALLL SOURCES GOING ON 12 YEARS EXPERIENCE AND AA/C KNOWLEDGE AS A MAINTENANCE ENGINEER SUPER. THIS SEALANT DID NOTHING, NOTHING TO STOP THE LEAK AND THEN ASKED FOR REFUND CHARGEDME A $25. RESTOCKING FEE .CHECK RETURN POLICIES BEFORE PURFACE. ANYWAY DECIDED TO TO AN A/C CONTRACTOR TO INESTIGATE LEAK BACKED ME BY 100% SAYING IF THIS SEALNT COULDN'T SEAL MY LEAK THEN IT CAN'T SEAL ANY LEAK AND WOULD BE HAPPY TO TALK WITH AMAZON ABOUT IT . I DON'T WANT ANYONE ELSE TO BE SSUBJECTED TO MY SITUATION !! BEWARE !!!

Best refrigerant leak seal in the market!! Very easy to install. I’ve installed this product in AC split systems ranging from 2-5 Ton. It does the job.

Easy to use. Danby wine fridge wouldn't hold a Freon charge.Installed this product,charged the Freon and the fridge has been working perfectly for close to thee months now.

Very easy to use!!
