49.5 mm x 40.5 mm x 7.5 mm. Silicone lubricant is highly recommended.
Suitable for the current lever groups on the market: they are used by Astoria, Brasilia, Bosco, Kees VDW, Londinium, Quickmill et al..
Each piston requires 3 V seals. The V seals are much softer and easier to install than the rubber ones.
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.
