what do you do to keep the olive tight on the pipe?

 

When you tighten the nut it should compress the olive onto the pipe forming the seal AFAIK. Should be REALLY tight like that.

 

The clue is in the name!!!

Compression fitting!!

Simple tighten it, job done!

 

Oh, by the way, don't crank it right up tight as you will crush the pipe and olive!

 

do the nut up mate! It pushes it into the joint and it squeezes the olive onto the pipe. could use a bit of jointing paste if you want to make sure it seals but its not necessary.
hope it helps!

 

i didnt do it up tight enough

thanks

 

 

i hate it when plumbers use jointing tape ... no need for it unless they are too heavy handed

last one that did it on one of my jobs caused the client to be charged around £600 labour for me to flush it out of their coffee machine bet i charge more an hour than tiff does

 

If theyre bad enough to be able to get it inside the pipe when putting it on then they shouldnt be in the job really should they? I said jointing paste anyway! you dont use tape on compression joints.

 

i know it was nearly a case of pulling the machin out it had got caked up in the water filter and electrovalves oh also £200 for another water filter forgot that

they of course denied all responsiblity .. but as it was on a quinetiq site they could not get out of it everything is documented .. bloomin military

 

crazy! Just for bit of stuff in the pipe!

 

i put ptfe tape on all the joints
and the stuff the pipe in as far as it will go before tightening up the nut
you can normally get it tight enough with your hand and then as you tighten it up with the spanners they start to bite
you can also "feel" when the olive has got tight enough once you've done a few

 

was really weired ... made all the water turn white and cloudy ... then it solidified as a white rubbery goo

 

never seen that happen before!

 

compression fittings nowadays are pi55 poor

i always use a water jointing paste(jet blue)around the olives and have had no problems

if you put it on the inside of the pipe thats another story

 

very true. Im still unsure why or how they would put it on the inside!
