How To Use Microbore Pipe For Central Heating

WORKING WITH MICROBORE PIPE

Flexible microbore pipe can be easier to work with than conventional rigid copper tube. But only if you know how to handle it.

To cut it, use a junior hacksaw. Ream out the inside carefully — you cannot afford to make the diameter any smaller than it already is. It is better to use solder fittings if you can get them — compression fittings are a little fiddly and delicate at this small size.

Before making a joint, use a rerounding tool to make sure the tube end is properly circular — it is very easy to squash it slightly as you cut it. The tube can be bent easily by hand, but for the tightest. Neatest bends you should use a bending spring. Once the tube has been bent, it tends to harden up and it is more difficult to bend again.

Never try pushing the tube — you’ll only kink it. A kinked piece of tube is useless.

Microbore pipe can be cut with a hacksaw. You will find connections at the valve are often more complicated.
