Copper deforms just enough under torque to even out every small irregularity, and that's exactly what makes it the material of choice for sealing rings on threaded connections.\u003c\/p\u003e\n\u003cp\u003eOver time, even copper loses its ability to deform – once a fitting has been loosened, the same ring often no longer seals reliably when retightened. A new ring brings the connection back to being tight, for little effort and even less cost.\u003c\/p\u003e\n\u003ch3\u003eAt a Glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e27 x 21 x 1.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eCopper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eSealing ring for threaded connections\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eLa Marzocco, Florence, Italy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWho It's For\u003c\/h3\u003e\n\u003cp\u003eFor anyone who needs a new sealing ring for a loosened fitting after maintenance or a service on their La Marzocco machine.
