Abstract
A press fitting arrangement includes a sealing ring to be housed within a bead of a press fitting into which a tube is to be inserted. There is at least one gap between the press fitting together with the sealing ring and the tube which is closed by pressing at least one portion of the press fitting. The sealing ring has at least one first portion along the majority of its circumference. Each first portion of the sealing ring has an outside diameter (SOD1) prior to fitment into the press fitting bead which is larger than the inside bead diameter (BID) and an inside diameter (SID1) prior to the insertion of the tube which is less than the tube outside diameter (TOD). Additionally, the sealing ring has at least one pair of diametrically opposing second portions, each second portion of the sealing ring comprising a recess between the two projections.
