Used for gas or water, but if using on lpg must use copper olives. I'm not qualified for oil but since lpg is in same group I expect they like you to use copper olives also.
There was that answer nice enough?

same as ordainairy elbow joints, but by people who can't solder, also usefull if something will need to be moved (easy to undo)
the ordinary elbow joints i got can be unscrewed easily and did not need soldering these just go smaller in the inside of the connection.i thought they was to increase the pressure in your taps.anyone know otherwise

No they don't alter pressure they just alter flow rate. Presure is governed by the mains pressure or the hight of your cold water storage tank. To alter pressure you need a regulator. restricting the rate of flow makes no difference to pressure, but it does reduce the amout of water that flows at that pressure.

They can only be used on gas if the fitting is accessible after it has been fitted. i.e. not under flooring or concealed within a wall etc.
so if i use them they will they make my taps run slower or fasterPaul Barker said:

Sorry, you are misunderstanding.. you can use compression fittings on water, forget about gas, you are not interested in that. The only difference in a compression fitting & a soldered fitting is that if you are cutting into a pipe that has been filled with water & you need to rejoin this pipe to newer pipe then a good idea would be to use a compression fitting. The only reason for this is because if you try & use a solder fitting, because of the water that may still reside in the pipe, as soon as you apply any solder in won`t run or `seal` because of the water in the pipe.That is why you would use a compression fitting because you can seal the joint mechanically i.e. with a pair of adjustable spanners or pump pliers & adjustable.
thanks for that answer i understand now cheersBamber gaspipe said:
