EasySeal-UV DYE 4050-11

Easy to use and works great!

Loved the built in check valve that prevents the sealer from leaking

Before buying two of these, I’d used a buddy’s leak detector and found several leaks in both of my unit’s evap coils. I bought some Yellow Jacket manifold gauges/hoses and used them to inject the Easy Seal into both units. That night we could tell both units were blowing significantly colder air (outside temp was 96 and air temp from the vent was 60.7). I’m really hoping this extends the life of our ac units - the last two years I had to spend hundreds to replace the lost r-22.

I HAD A VERY SLIGHT LEAK. SO SLIGHT THAT IT WOULD BLOW A BUBBLE, BUT NOT BREAK IT.. HAVE A 5 TON UNIT, BOUGHT A SEALANT FOR A 7.5 TON. INSTALLED IT EXACTLY PER DIRECTIONS.. NEVER SEALED THE LEAK.. I KEPT ADDING FREON TO SEE IF IT WOULD SEAL AFTER SOME TIME.. 4 WEEKS LATER STILL LEAKING.. I WAS HOPING IT WOULD WORK LONG ENOUGH TO GET ME TO SPRING SO I COULD FIX IT PROPERLY.. NOPE.. SAVE YOUR MONEY !! THIS PRODUCT DOES NOT WORK !!

Did not even begin to help locate and seal a minute pin hole leak in evaporator coil,ended up pulling out evaporator pressurizing coil and using bubbles and leak detector found pin hole leak was able to repair leak,this product was a waste of time and money

Small pin hole leak, lost 6 lbs over 2 year's... Added this per directions and lost all the freon added in 2 WEEKS....This DOES NOT WORK........
