La Spaziale Group-to-Boiler Heating Element Gasket This gasket seals the group-to-boiler connection on La Spaziale Gaggia TE/TD heating elements. It also fits La San Marco Sprint model heating elements. SPECIFICATIONS Dimensions: 50 x 40 x 2 mm COMPATIBILITY Fits: La Spaziale Gaggia TE/TD heating elements Also fits: La San Marco Sprint model heating elements INSTALLATION Simple DIY swap during heating element service; drain the boiler first to avoid spills. PRO TIPS These gaskets compress and harden with heat cycling over time, if you notice mineral staining or slow weeping around the element flange, replace the gasket rather than over-tightening the mounting bolts, which can crack the boiler.
