I have questions when I try taking shraders out sometimes they are stuck in damaged I've tried using needle nose turn and pull to take out but I'm cautious because the last thing I want to do is damage the threads. Is there another way of taking this out?
Also I've been doing the removal and install of shraders all wrong imma follow your way. I'm one of those that pulls vacuum then put shrader back in then charge system.
You think that putting in 1-2 pounds and the valves will be ok?
Do yall do work in Tampa,I'm in Tampa trying to find an HVAC/r company to work for.
fuck i love your vids. thanks!
Are the valve core seal colors identify the operating temp and pressure?
Hi can this tool be uses every time I perform a vacume…when maintenancing the AC condensor lines in the unit unit???
Can you use these to add refrigerant using wireless probes on one port and the hose from the refrigerant tank on the other?
I find pressure behind valve caps 7/10 times, even after replacing the core.
From the Lennox IOM: "Each valve is equipped with a service port which has a factory− installed Schrader valve. A service port cap protects the Schrader valve from contamination and serves as the primary leak seal ."
I don't like having that many connections when trying to pull a vacuum. I would rather have the vacuum pump run longer than deal with all those potential leak connections.
Really awesome video
Thanks for a wonderful explanation
excellent artwork and animation
Fascinating video because I just recently came up with a solution of adding RX scavenger to any burn out systems. Super simple process and it makes everything go very smooth.
Thanks for sharing this video, God bless this channel and more power.
Up in NJ, & suspect others, there is a LIABILITY situation, in that IF. I AM the LAST PERSON SERVICING a residential unit I MUST INSTALL LOCKING VALVE CAPS , to negate HUFFING , , there was a SCHOOL IN FLORIDA where the chiller was ALWAYS SHORT OF REFRIGERANT , several leak checks provided NOTHING ! Contractor installed a camera into a video recorder, then FOUND THE ANSWER,,,
HUFFING, SO until LOCKING CAPS, WERE INSTALLED, , no more huffing hey were speaking of enough refrigerant , to disable a big chiller ! Cheers 🇺🇸🇺🇸🇺🇸🇺🇸
Many moons ago, I HAVE HAD SCHRADER VALVES DAMAGED MY sourse for removing them ? In AUTO STORES they do sell a core tool which looks like a CROSS, 1 end remove schrader valves, 1 end is an EASY OUT which I HAD NEVER HAD ONE I COULD NEVER REMOVE with it one end has NO USE IN OUR BUSINESS, ITS A TOOL FOR EXTERNAL THREASD ON CARS, THE OTHER ENDBEND CHASED THE SCHRADEER THREADS INTERNALLY . I have had 1 about 30 or more years, butt core removal tools, The first 1 was ROBINSIR, NEVER COULD GET REPAIR PASRS, THEN HAVE FEW YELLOW JACKET & APPION , one of my YELLOW JACKET ONES EVEN HAS A TAP TO USE A THERMOMETER AT THE SAME TIME . CHEERS 🇺🇸🇺🇸🇺🇸🇺🇸
Happy holidays. Thank u. Your helping techs all around the world put food on there family's table.
Nice job and video
Thanks!
So schrader has to be out to pull vacuum but in to charge the system. If you can push liguid thru a schrader you should be able to pull vacuum it thru a schrader
Do you care to recommend a brand for everyday core repair use? I have two Appion’s and they won’t always get a core out, even if you have it just right enough to not leak.
I had an old one with no mane on it and it would pull out any core but it broke. The Appion’s are great for vacuums and will put any core in after a vacuum but some systems just won’t pull them under charge.
