I like to drop in a little mechanical item from time to time, so here's a nod to AvE with a teardown of what turned out to be a beautifully designed and machined stopcock. The overalls I mentioned were the Carhartt R28 carpenter overalls with a strong built in tool pouch that seems to be popular in the USA with plumbers, sprinkler fitters, elevator mechanics and other trades that use loose hardware.
Paul of Brix Workwear in Ireland generously arranged a set of the standard R01 bib overalls as a gift, so that technically makes him the current official workwear sponsor of bigclivedotcom. He didn't ask for a link, but here's a link to his website:-

The brass stopcocks (if they are actually brass) are a common item usually sold in 15mm and 22mm pipe sizes (plus some bigger ones.) When you see the amount of machining in them it makes the price remarkable and suggests major mass production in a competitive market.
A bit of research suggests that the graphite may have been a graphite packing washer optimised for high temperature applications. I've never seen it used in an application like this before.
Note that the adjustable spanner was not up to AvE's standards.
The compression glands are supposed to be tightened until they grip and then a percentage more to fully compress the olive onto the pipe. Personally I overdo it out of mild paranoia of pipes popping out of fitments.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Any chance of some private pictures of this nicely machined cock in close-up? 😇
That video title from the US perspective.

If I had the gas how they made that weird bolt, I would say that they probably put it in, crimped it, and then machined the threads afterward.
never heard of AvE being pronounced ae-v
"Nicely machined cock" has a different meaning where I come from
The secret to that seat getting mounted in the stem is a combination of heat and cold. The stem gets heated, not a great deal but it does get heated, the seat gets chilled with nitrogen or some other super cold gas which causes it to contract. When everything comes back to room temperature the square peg is stuck in the round hole.
I have seen it done using an induction coil to heat the stem, negating the need to cool the seat, but on a precision milled item like this one I would gather they don't want to risk deforming the stem.
On a cheap one they would just super heat the end of the stem, pop in the seat, and let it cool. Then 15 years down the road let the homeowner deal with the fact that the stem has broken off from the seat due to the stress from manufacturing.
I just want to say how awesome it is that I have the answer to a question you've asked. I so often feel dumb trying to figure out what you're talking about. 😎
My comment seems to have DISAPPEARED? Not sure WHY? It was no more "rude" or "offensive" than the video title? Has nobody got a SENSE OF HUMOUR any more???
Gate valve vs globe valve kinda…
Had a leaky tap that oozed through the shaft and couldn't get it to stop. Went to a plumbing shop and the guy said, "Oh just undo the lock down nut and shove in a bit of PTFE tape." Worked a treat and years later is still fine.
FYI, in my experience plastic olives are far far more reliable than copper ones. As you mentioned you shouldn't clean the pipe end with sandpaper and even more importantly the pipe end itself must be perfectly straight, so hand bendable copper from rolls can't be used with copper olives. Not so when you use plastic olives. They form a better seal on all types of copper pipes whether thy are perfectly straight, new or old. Although the cut end must be as close to perfectly round in all cases.
Great teardown. 🚰 🛠
Thanks for sharing. 😎👌🏻
Nice cock bro
Oh lord, don’t suggest that BC investigates a gate valve. hehe
my grandfather's bungalow in India still has a really similar tap, it is +80 years old.
he changed the washers only 2 to 3 times only.
It still works as it used to back in the day when he was a kid.
I always thought it was pronounced, Ah-vey.
does big clive dream of electric chickens?
