Steam Wand Spring Seat - Brass, Multi-Brand Fit A brass steam wand spring seat that fits Rancilio, Brasilia, Elektra, Fiorenzato and Promac wands, among others. It does the same job as Rancilio's current R_1248, just in brass instead of PTFE, Rancilio has since switched to the R_1248 exclusively. SPECIFICATIONS Dimensions: 12/9 x 5 mm tall, 7mm I.D. hole COMPATIBILITY Fits: Rancilio, Brasilia, Elektra, Fiorenzato, Promac, and other steam wands using this spring seat size Replaces: Rancilio R_77; also cross-references to Bianchi 04058316, Brasilia 06508.0.00.04, Elektra 01913014, Fiamma RST 5.0.025.6508, Fiorenzato/Grimac A2200003, Lavazza 10084136, Nuova Simonelli 07300293, Rancilio 23119005, Ricambi Gardosi R202, and Vibiemme RACCBUSASTSNK Works with: Steam wand spring assembly; functionally identical to Rancilio's current R_1248 INSTALLATION Simple DIY swap when servicing the steam wand tip and spring. PRO TIPS Brass vs. PTFE matters here: brass seats can gall slightly against a steel spring over years of heat cycling, while Rancilio's PTFE R_1248 self-lubricates and won't corrode, if you're rebuilding a wand from scratch on a Rancilio machine, the PTFE version is the better long-term choice, but this brass version is the right call for cross-brand compatibility.
