Olive removal!

[sticky01]

Hi

I'm just doing some work on my central heating and wanted to replace some of tye radiator valves that are old and seem to be in poor condition.
However the new valves that I've bought have different sized nuts on the 15mm pipe to the old ones. I need to remove the old olive to get the nut off. Is it best to do careful use of a junior hacksaw, or an olive puller, similar to this

Toolstation > Hand Tools > Plumbers Tools > Olive Puller

I see on fle bay they goy for about £13.


Even if I get them off am I likeley to get a good seal with new nuts and olives on the old pipe.

Cheersw Sticky

You can use a hacksaw and a flat screwdriver.
If the olives aren't too crushed you can give them a little squeeze with pump pliers and turn it back and forth, it'll loosen and you can pull it off.

cut part of the way through with junior hacksaw, then use a flat head in the cut, twist to snap olive.
put new nut and olive on, pinch up, back the nut off, apply some jet blue around the olive tighten up

Olive removers can damage the pipe. Its best to do as previous posts have said and use a junior hacksaw and screwdriver.

I use jet blue too

I've got that olive puller as well as the Monument 15 & 22 olive cutters.
I've had them for a couple of years now. They're all still in the original packaging unopened.
I've managed up to now using the methods above or just knocking the nut towards the olive with a spanner & hammer.

These are great, i have them in 22mm and 15mm

but you can take them off with a hacksaw if it's not something you do often, or as already mentioned pull them off by grabbing the nut with a pair of grips

It's much more likely that you will damage the pipe with a junior than with an olive removal tool. I use the Rothenberger one.

Junior hacksaw blade and terminal driver.

Cut the olive with a junior hacksaw on an angle to the pipe, not in line with the pipe. Much easier this way & you won't hit the pipe with hacksaw blade. Just cut through 3/4 depth of olive & use a sharp flat blade to split olive.
