GASKET ORM 0102-25 PTFE. 15.2 x 10.2 x 2.5 mm.
Removing and replacing these can be extremely challenging as the PTFE has very little elasticity. We recommend removing the tip, then the rubber heat guard, then the nut and reassembling in reverse. These come already installed on the newer steam wands, replacing the old S_260 rubber o-rings.
