Thank you for mentioning the magnetic locking caps and tool! Our furnace went out, and the technicians replacing it needed to get to the AC refrigerant lines, but it has the locking caps on the valves and they didn't have keys or a tool. The previous homeowners never mentioned the caps, and we haven't had the AC serviced since moving in, so I had no idea they were there. Everything I was finding online talked about the newer style that take the keys, but ours have no hole for a key, so none of the other jerry-rigging solutions would work beyond cutting into the sides of them. This video is the first one I found that mentioned the old magnetic style caps ever existing and the tool to take them off. I was able to similate the tool with a couple of strong kitchen fridge magnets, and then I just spun them off with my fingers (they probably weren't tight enough to begin with)! Thank you!

@@love2hvac I've been watching your videos for some time now, haven't noticed many flaws at all. I'd say they're more helpful than you might think. BTW, on service valves, I like to squirt a few drops of compressor oil into the top around the edge before installing the cap.

Damn fine videos. Well done.

Thank you

nice

Since the high side has more pressure is the process the same? Does the low side fail more than the high side? Do these values loosen up often? Do you have a favorite replacement value and tool you use?

Biggest issue is cleanliness. Tecks don't take care of thir hoses and drips them, drifts sticks the the hose ends and then the put the dirty hoses ends kn the unit pushing contaminants into the valve. Also letting the caps drop into the dirt and putting them back on and leaving caps off letting them fill with debris and dirt. Any brand will work but I do like my Appion brand. www.trutechtools.com/mgavct?gclid=Cj0KCQjwnueFBhChARIsAPu3YkSytCD52HqzeT6bXikpa7-kJnl5U_Tig1h3gztW2aPPx_EyGv2EOKAaAiCuEALw_wcB

Do you have any review videos or opinions on the cheap Chinese digital gauges like the DUOYI DY517a for very occasional use? My main concern is if they are accurate enough or if they give unstable readings and will lead to wrong charge in system... Thnx!

Can we add o-ring to hex caps?

@mattthie9993

If the hex caps are flared on the inside, then no. Flared fittings for a pressure seal via the metal-to-metal flared surfaces of the male and female flared fittings, so an o-ring or any other sealant inside the flare would get in the way of that seal forming.

How can a plastic cap hold 30 bar 🤔 next thing will be fridge lines in plastic 👎 Keep up the good work all the way from UK👍

the plastic & o-ring are just meant as a little diagnostic tool. But yeah, they could use proper brass caps in cars too...

Its the scraders job to seal the system caps are for protecting the scraders from dust/debris. The good ones do act as a backup. Its the same with cars tiers 3bar no plastic cap can keep that in.
