me googling this after years and my washer leaks:

Has anyone experienced the copper rubbing off on tools and tiny little shards of copper coming off their copper washer when hammering, wondering if I got fake copper washer from Amazon?

Good to know! Thanks for sharing.

Does quenching not harden metal?

Amazing!

I do this with all my brake caliper banjo washers

Where can one be purchased

My 2015 Triumph motorcycle uses an aluminium drain plug washer I believe, it's certainly not copper coloured. Anyone heard of this before and how to anneal them??

This is brilliant! Copper washers are one of those where you think "Well, just get a new one," but you invariably never have the right one to hand when you need it. And when you need it, it's always on a Sunday afternoon, the shops are shut, and you won't be able to pick up another one until next Saturday!

I learned this at school.

don't quench it... that's a hardening process.

Too cool, thanks! So many things I don’t know….

#### *I don't understand?* 🙋 Plz correct me if I'm wrong: heating a metal red hot softens it, right? When it's red hot, immediately throw it into water will immediately HARDEN it, instead of softening it, no?

I did this for years with motorcycle head gaskets.

Pennys save pounds 😂

The hugely profitable copper washer sales mafia have taken notice ...

If you put hot copper washer into alcohol instead of water it will not form any oxide on the surface of washer. But you should be careful - alcohol could catch fire. Just put a lid on a jar with burning alcohol and fire stops

Super cool trick! Thanks!

Thanks , I wish I knew that before I have done my diesel injectors on my bus . Couple of them were leaking after reinstalling . South Africans know how to do things .

You are a cheap date.

😴😴😴😴👎👎👎👎

You need to record at a higher audio level I should not have to turn up my audio to almost 100

YA QUENCHING MY THIRST ON A SUNNY DAY MAKES ME SOFT UNTILL IVE HAD A FEW TOO MANY KLIPIES THEN I GET HARD UNTILL SOME JELOUSE OKE GIVER ME A VAREMA KLUP JONG!!!!

Works with all sump plug washers and also copper brake banjo washers. Also a good idea to flatten any deformation of the washer with a flat headed hammer and then rub on a nice flat surface of very fine 1000 grit emery paper. Re aneal. Beats me why modern mechanics charge people for a new sump plug and washer every oil change

Doesn't make any difference to copper or brass weather you quench or leave to cool it will soften.

Thank you Tony!

First, dunking in water is a MYTH! It does nothing to soften the copper. it is the HEAT that does the softening. Might knock a bit of scale off, but that's it! You do a disservice by propagating this myth!

pop!

That pop to red is something else! Thanks for posting

Done this to get the copper wedding ring off my wife’s finger,now she,s not talking to me.

Use nylon washer,

i knew about annealing copper . but i never realized this application , thanks

Heat it, beat it, heat it, done 😉

* pop * noice

I heard "I've godda little video hyaa" and I IMMEDIATELY thought: "Heeeeeyyyyy!!! my fellow countryman!!"

Works for older thin copper head and base gaskets too (in a pinch). But Head gaskets? I would still keep a new spare, Ive seen them get to the point that with repeated uses they deform uneven and leak. Still its pretty amazing this> copper and leather were the two most common methods for seals and gaskets for a century before synthetics.

Soft washer with no springiness = leaks ?

Is it just me or does the ring really changes colour at 2:21 simultaneously with the pop?

Who's neil?

loool and all these idiots screaming you should use a new washer everytime you change the oil.... I just reuse the old one over and over and had never problems with leaking plug screw.

Once you plop you can't stop.

Wow that is cool!

Interesting

Soften brass washers help

Great tip thanks mate 🇦🇺

This was really interesting, but I just bought them in bulk cheaply on Ebay. Probably cost less than the propane and time to anneal.

The quenching step is optional for copper.

So is this allows the used copper washer, to be reused on the oil drain plug?

👍

This works on copper tubing as well so you can bend it without it kinking.
