Marley

With the HT lubricant from Marley you will no longer have problems with difficult-to-slide HT and KG pipes. The lubricant is simply applied to the outside of the pipe section, which is difficult to push into the sleeve, then the parts are put together. Afterwards, however, you should pull the pipe out by about one cm, as the pipes expand when the temperature fluctuates, leaving enough room for maneuver. The lubricant does not necessarily have to be used for HT or KG pipes.
