The "multilayer" tube makes it very easy to produce pipes for connecting sanitary and heating equipment. It is presented in straight bare tube of 2,50m or in bare or sheathed crown (blue or red) of 10, 25 or 50 m. Various types of fittings are adaptable, automatic or compression (straight, angled, tees, reduction sleeves) and allow to connect it to copper pipes. A pipe cutter, a chamfering device, a bending spring and a disassembly device are the only tools, perfectly adapted, which are necessary for its implementation. No need for glue or welding and even less key...

Preparation of a multilayer tube
1. Mark the dimensions on the site with a pencil or felt pen on the pipe. 4cm must be added to each measurement taken between the outer ends of 2 fittings. Indeed the tube sinks 2 cm in each connection tip to be in place.
2. Position the cutting disc of the cutter on the mark made and rotate it around the tube to make the cut. Make sure that the cut is perfectly perpendicular to the axis of the tube. The tube cutter has the advantage of making a much cleaner cut than with a hacksaw or even a jigsaw equipped with a suitable blade because its use prevents any external deburring.
3. To prepare the interior of the "multilayer" tube, a multi-key accessory is at your disposal, specially equipped with an iron capable of producing the internal chamfer necessary for the good junction of the tube in the bottom of the fitting.. The three branches correspond to the three inner diameters of the three available dimensions (16, 20 and 26) in this material.
4. Engage the accessory in the cut tube, turning it until the guard touches the tube cut. Chips of the inner layer attest to the completion of the operation.
5. With one hand, place the primed end of the tube at the inlet of the fitting and push in firmly while holding the fitting with the other hand.
1. Each tube properly engaged in its fitting will show a green seal visible in the control lights around the base of the fitting.
2. Special brass fittings allow all "multilayer" tubing to be connected to copper pipe fittings.
3. A spring adapted to the diameter of the tube worked, makes it possible to bend it precisely if one wants to avoid putting too many connections on a tormented circuit.
4. This revolutionary tube is composed of an aluminum core sandwiched between two adhesive layers on which adhere an inner layer of composite material and an outer layer of the same composition.
