I worked in auto repair. Whenever I hear something about refrigeration and Japanese products, I think of the 1985 and 1986 Nissan Maxima and the 1997-2001 Honda CRV, two cars prone to having the A/C compressor fail and then destroy the condenser with junk from the failed compressor. Another common problem in cars is that the Schrader valve where the A/C hose meets can fail and leak refrigerant in seconds. If you are lucky, you can thread a new Schrader valve on the existing components. If you are not, you might have to buy a new refrigerant hose which can cost anywhere between $150 and $350 depending on which car it is in. In auto repair, there is typically one machine for A/C which is about the size of a rolling tool cart. It has a vacuum pump, refrigerant reservoir, computer, and scale all in one unit. These repair shops often don't maintain these machines properly and that often means refrigerant blowing out of a failed gasket and means you might lose the repair job to another repair shop. Those shops typically don't maintain other equipment and hundreds of automotive lifts are death traps. However, learning to repair automotive air conditioners doesn't require much time to learn and the jobs aren't difficult to do. I live in Florida, and the demand for A/C guys exceeds the supply. I know the situation is similar in other hot parts of the USA, because I have many family members who live in Texas and pay a high price for automotive A/C repairs.
This is the best how to video on changing the gaskets and so important. Being in maintenance I don't do AC everyday so it's easy to forget the little things.
Thanks Steve, My basic air conditioning class here at Elgin Community College is starting on charging and recovering refrigerant. This video will be required viewing, so as to show them proper manifold hose care. "You're a difference maker." Woody
Awesome video Steve. I would love to see you do an entire series, "Just for the New Guys." Because sometimes what you think you know you really don't know.
Made a trip to get other things at the supply house and grabbed 4 bags of the Yellow Jacket 19020. Thanks Steven, You the Man.. Already swapped out the oring on 2 of my manifold sets.
Dude. I never knew you could replace that. I been buying new hoses too. I just happened to look behind the counter as I was buying some Freon yesterday and noticed the baggie of gaskets. Lol. Then the other related products next to it. Thanks for the video
Good idea to buy new test/charge hoses every year because they can leak. If you’re using test/charge hoses for vacuum and you can’t pull a decent deep vacuum or it keeps breaking on you, then the hoses themselves are one possible reason for this. Better to use a vacuum manifold and the heavier black rubber vacuum hoses instead. Even then you may have to change the o-rings in the fittings from time to time.
add a dab of yellow jacket grease to the outside new seal and Schrader core end, and they jump together and come out so easy when its time to change this guy half asses it...
Question: Is it possible to use flexible rubber hoses in a mini split system instead of copper hoses? I want to build a portable mini split air conditioner that can be used to cool any room. The system would have the compressor sitting outside and the indoor wall unit mounted on a portable stand. The hoses from the compressor to the wall unit would have to be flexible rubber instead of copper pipe and be about 20 feet long. The compressor itself will have a receptacle for electricity to be plugged in to power the system. The idea is to make the system portable and to be able to use it in any room. What I am not sure of is whether the flexible rubber refrigerant hoses will hold the charge for an indefinite time without the refrigerant leaking out.
Did you ever figure out why you needed to use a 5/16 gasket on another hose? Was it maybe from memory on another hose you could not locate at the time for the video? I would like to know because it would help me in considering non-standardized gaskets being a possibility. Like, it will always be 1/4 gasket for model/maker this, this, and that..., and 5/16 for that, this, and that etc.
i have a 4 valve imperial gauge set up. with the high pressure valve closed it sucks in refrigerant into the valve body. Is their anyway to diagnose t his problem? I pulled the knob and diaphragms out, all that looks descent.
Thanks for the videos! You made reference to Japanese brands being inferior but I'll bet you meant to say Chinese. Back when I was a kid (60's-70's) Japanese products had a bad reputation. Today in general they are up there with the best. Though Chinese products in general are cheap and unreliable there is a small but growing segment of Chinese manufacturers that are producing some of the highest quality products available. Unfortunately a lot of high quality American made products are mostly assembled from high quality Chinese parts or raw materials.
Hey Steve thanks for showing us that . I had a question regarding your recent video on the flaring tool. I tried it out the other day and it got HOT, I mean smoking hot. Is that ok for the drill ?
Hey Steve, I want to run something by You (off subject), what do You think of Stay Brite solder on refrigerant lines? It's easier than brazing, but risky as far as restrictions...?
mine have teflon gasket instead of rubber do they broke after few weeks too ?because i have been using it for like 3 month ,they still looks good,but i dont know if i should replace them or not

Steve I'm glad u made this vid and showed how to replace them , there are alot of guys that just buy new hoses every season and waste there money .
justin henning you might be right

Steve Wood thanks for the support
Man, I lost a valve core depressor the other day. Had no clue how easy it'd be to change out everything. Thanks so much for the know how & how to!!!
Awesome video Steve. I would love to see you do an entire series, "Just for the New Guys." Because sometimes what you think you know you really don't know.
Tim Herr i might do that
I would watch for sure. I'm impressed by your willingness to help out the new guy.
I've known you could replace them but nobody showed me how. Makes sense now. Thanks
Great Job Steven, Your right! got to maintain. Haven't seen anyone yet come up with this type of video, but very important.
Mike Urnise good info to fix/maintain hoses
Made a trip to get other things at the supply house and grabbed 4 bags of the Yellow Jacket 19020. Thanks Steven, You the Man.. Already swapped out the oring on 2 of my manifold sets.

quite right steven i only ever used yellow jacket and imperial gaskets in my hoses but could never fing nylog over here in the u.k
Hello my friend .. thank you so much for teaching how to replace this o'ring !
I was having trouble changing.
Im from Brazil ;)
Good video, wish I had watched this 1 months ago! I have 3 sets of hoses now. but it's all good for spares and when I need a longer length hose.
Matt HVAC/R you can always use extra hoses for recovery ect .
Great tool maintenance demo Steve.
teh60 i like these type of videos
Nice tip Steve, I have to change mine about every two weeks, And yellow jacket has the core depressors part number 19302. Bag of 10 for about 9.00 $$
Arnie Grote yellow jacket is good stuff
Thanks Steve, I am new in this filed and your videos realy help me to improve knowledge. Thanks keep the good work.
+Octavio Delgado thanks for watching
Sir!!
Thank you for making this video and helping out us new guys.
thanks Steve.....i just got mine fixed......keep up the good work bro....
Very good tip. Just replaced all mine today. Thanks
I have had times that I could not find them on my truck and had to turn the old one's upside down till I made it to the parts house.
USMC 1961 i try to stock extra rubbers in the truck
In a pinch, flip gasket over to get you through till you can replace them. If you can pull it without breaking it that is.
Great tip and video Steve
Harry Dickson tech tip videos
good topic - thanks for the video Steve.
Straycurrent good topic for sure
I got caught in a pinch once and made by with flipping the gasket over. Try not to scratch the inside of the brass barrel with the hook tool!
Awesome video Steve!
israel contreras thanks for the support

Can you do a video on how to change the valves on the hoses?
Good video Steve.
Jon Hexom thanks for the comment
Thank you i really appreciate it will help me in the future
Alex Sisto good deal

Nicholas CeeA thanks man
very helpful , its really important , thanks
+edebawy yes its very important for sure
Thank you Steve! Great useful video :))
George Ballard thanks man
That little part to push the Schrader valve in. Are replacement parts available?

Nice job ( Steven )
Shit I've been buying new hoses..... 11 years and no ones ever showed me that!
And I came online to order a new Hose, but now am looking for a much cheaper Gasket Set. Thanks Man !
Don Ward got a nee pack of 10 gaskets for $4 and some change, yellow jacket brand (says fit all 1/4” hose).
Thanks, exactly what I need to know.
Very informative Steven! Can I do this in the garage, or do I have to do it in Momma's basement??
Brad1237202 always better in mamas basement
🤣😂
i have a 4 valve imperial gauge set up. with the high pressure valve closed it sucks in refrigerant into the valve body. Is their anyway to diagnose t his problem? I pulled the knob and diaphragms out, all that looks descent.
thanks for taking the time to put this together

what about the gaskets 4 vacuum pump hose the thick one? can you do a video on that?
Thanks Steven
Hey Steve thanks for showing us that . I had a question regarding your recent video on the flaring tool. I tried it out the other day and it got HOT, I mean smoking hot. Is that ok for the drill ?
Hvacrookie86 yes it gets hot to anneal the copper and it will not split
Like it
Rob HVAC thanks rob
'what about the white ones.. Don't know what they are made of. Are they replaceable ?
good stuff brother
Hybrid Mechanical thanks for the comment
Hey Steve, I want to run something by You (off subject), what do You think of Stay Brite solder on refrigerant lines? It's easier than brazing, but risky as far as restrictions...?
You use nylog everything you pull a vacuum?Will it leak if you don't?
super tip steve
Why use Nylog on one end of hose and not the other end?
7:48 where did you get the short hose? Does it has depressor at one end? Thank you
mine have teflon gasket instead of rubber do they broke after few weeks too ?because i have been using it for like 3 month ,they still looks good,but i dont know if i should replace them or not
+Tonny Cassidy look at them good you can see when they start to wear
What about the back part of the hoses
Lol I have so many low loss hoses bc I thought they were just poopy
nice vid. :)
***** something different
steven lavimoniere :)
wow I thought you had to screw them pin in????
Steven,
Breath a little harder into the mic 🎤
