What is an Olive Roller tool?

[TMHM]

Showing my ignorance here, but what is (apart from the obvious) an olive rolling tool? I have just been speaking to a mate that swears he used to have on. Its a device that uses a ball bearing??? to roll a lip into a pipe to be used as an olive. Do you guys use one? Can you still get them? Pros and Cons?

Edit: should have called it a pipe beading tool

I first saw one used around 50 years ago.
Never owned or used one personally.
Issues I can see are you have to get the position of the roll correct, no adjustment afterwards.
And it may be difficult to get the roll tool into some tight locations.
And if the joint is split at a later date you can't just fit a new olive and tighten up.

I like the idea tho. this one seems simple and effective?

The one I saw , 50 years ago, had a Tee handle, so was more bulky than the one above which is Imperial sized.
I know they've been mentioned on here before and someone posted a link to a Metric one.

They're used when you need a joint between a copper or aluminium pipe and a flexible hose. Fairly common inside machines and engines. In domestic plumbing you'd normally just use an off-the-shelf 'hose connector'.

Called a 'Crox Tool'.

We used to use them quite often during Fit-Off's of hot and cold water.
Mainly before Flexi connectors were available.

I bring mine out from time to time to show off to a 'Newby' who thinks they know it all.

Far better than an olive because the pipe is altered and the nut grips the pipe. No chance of slipping out as with an under tightened olive.

It will still leak of not tightened properly, but generally won't flood as per a slipped olive.

Hey Oz, could you use PTFE instead of Himp?

"Himp"

Loving the Aussie pronunciations here.

He's a Kiwi - not an Aussie.

Can't you heat the difference?

You can use PTFE - if you do, wind in on in reverse as you would do on a thread.
Doing the nut up will undo the tape.

I'm not so fussy as this KIWI !!!!, I roll it over the groove also.

Sorry, no I can't really. I've never paid enough attention but I am now determined to learn.
