Lu-Hawk R134A Adapter Kit, Self-Seal & Puncture Can Taps, Core Tool

Just as described and work great

This is a good adapter and valve kit for AC charge cans. Attaches easily to my manifold set as well as some other hose/guage connectors. Contrary to some other reviews, it fits several different r134a cans and works for self sealing and puncture type cans.

1st off these seem to be made of great quality, shipping was also great with Prime... I only did 4 stars because I'm not sure if its the product or maybe its the freon cans, but after pulling a vacuum with a manifold gauge set, the first self sealing can went in great, the second can, it wasnt letting out any freon, until I slowly started screwing in the tap & unscrewing then I finally got it in a certain area, then onto the 3rd can there was nothing at all, I also tried using the piercing tap with no luck, so I grab my hose with a gauge that was made for both self sealing and non seal cans and it worked great, so I am not sure if it was the taps itself OR the Walmart SuperTech cans that didnt want to cooperate but at the end the job was successful..

I've completed only three AC repair or conversion jobs, and I believe being successful relies much on operator input. This kit provides two different valves. One is used for the re-sealable type cans and one is used for a puncture / one use type of can, seeing as you can't shut it off once it's punctured. The only cans that have been made available to me are the re-sealable type. These little buggers proved to be tricky seeing as there is a fine line between overdriving the sealer and basically making it inoperable or just finding that sweet spot. I've learned to try to listen for the actual flow from the can into the manifold gauge. The bottom line is at these tools worked fine. I think operator capability and input is key, and a lot of the negative responses, not necessarily related to this brand, but others as well aren't necessarily based in fact.

just got to use one today...they are very well made worth to have ,,,

I used this to recharge my system using the 12oz cans through my manifold gauges. The adapter fit as it should and did not leak. Just a word of caution the new 12oz cans with the auto reseal got pushed completely out so now i have to leave my charge line hooked up to the gauges.

This type of can tap is notorious for having poor hose threads and inferior sealing. But these Lu-Hawk can taps are solid! No leaks at the hose threads or around the valve shafts. They simply work like they're supposed to. And compared to others Iv'e used, these are by far the best. The quality is there and they're all solid brass, not pot metal or zinc or crappy aluminum alloy. When you're working in 100+ degree weather and you put freon through the lines at 30 to 40 degrees below zero, the solid brass won't shrink and start to leak. I rarely give anything a 5 star rating so these are a solid 4.5 stars, at least.

I purchased these as my only can taps were the puncture type and the cans now are the self-sealing type with a built in valve. As the cans have a valve, depressing the valve by turning the knob on the tap is the way to open the valve. However, doing this with the Lu-Hawk resulted in no flow of refrigerant out of the can. I got another can of R134 and used my old puncture-type can tap and gently find the sweet spot where the puncture tap would depress the valve in the can and refrigerant would slowly flow out of the can. After that, I returned to the first can since the Lu-Hawk tap was still screwed onto the can. I turned the knob back a bit and then refrigerant flowed (very slowly) out of the can. There was barely enough pressure to purge the charge line to the manifold.....I had to give it time to build up enough pressure in the line! So they did kind of barely worked for me.....but not as they should have.

Works good, as advertised. No issues on self sealing cans.

Sirven

Funcionan bien y buen precio,

Worked as expected on a 1996 K2500 7.4 Suburban, 2015 Sierra 4WD SLT to replace evaporator core. Vaccuumed and recharged the systems

No es compatible con latas autosellantes. La rosca es diferente y por lo tanto no se puede usar.
