La San Marco Group Head Gasket 64 x 52 x 5.5mm

Perfect fit & performance - (+ used white silicone food safe grease @ installation) - just what I needed to successfully use my new aftermarket bottomless portafilter (good ... but would have preferred an OEM one - if available) .... without blowby at the old hard rubber group head gasket. Maybe next time I need Group Head Gasket - a LSM Silicone option will be available??? Regardless .... Thank-you Espresso Parts! Vaya con Dios ps. excellent packaging too. pps. & fyi - the way under-rated LSM group is AWESOME for doubles, triples & even .... EXCELLENT SINGLES too ....
