Cafelat Robot Piston Seal

Cafelat Robot Piston Seal

Piston seals are subject to wear and tear with the pressure it needs to withstand. These are Cafelat’s own silicone piston V seals for the Cafelat Robot espresso maker, same seal for the current lever groups on the market. Each Robot piston requires 1 V seal.

As with any silicone seal, you should only use food safe silicone grease to lubricate them, do not slather it on, a sheen is sufficient. Dow 111 is a good choice.

Please note that although the gaskets are strong under compression, you should never use a sharp tool like a screwdriver to install them. This may tear the silicone.

Size for modern lever piston seal (V-ring): 52mm x 40mm x 6.75mm (Red): SGS Food test report
