Pipes and various connecting pieces are connected quickly and easily by inserting the plug end into the groove advertisement and with an integrated rubber seal. Prior to joining pipes and fittings, the contact surfaces must be clean and undamaged.
If the required length of the pipe is shorter than the standard one, cut the pipe straight (with a fine-toothed saw) and grind the end edge at an angle of ~ 15 °. Lubricate the chamfered edge with a suitable anti-friction agent (grease for rubber seals, silicone oil, soapy water), which must not damage the seal or pipe.
Push the plug end of the pipe into the nozzle of the adjacent pipe or connecting piece with a slight rotation to the limit. The final position on the pipe is marked with a pen, and then the pipe is pulled out by about 2 mm for each running meter between the joints, but not more than 10 mm, which allows to compensate the stretches of the pipe due to temperature changes.
Deviations of the pipe in the head from the direction of the pipeline must be avoided. Pipe bends and other connecting pieces are used to change the direction of the route.
