The Writing Desk Silicone Grease
The Writing Desk Silicone Grease
£1.39
Professional grade pure silicone grease for lubricating the seals on all types of fountain pen filling mechanisms. Perfect for lubricating piston fillers (eg Pelikan, TWSBI, Lamy 2000 etc), vacuum fillers (eg Visconti Homo Sapiens, TWSBI Vac 700, Pilot Custom 823 etc) and for the servicing of all piston converters.

Supplied in 3ml clear plastic jars containing approx 2ml of silicone grease (which will probably be enough to service hundreds of pens). Apply very sparingly to the inside of the barrel or converter using a non-metallic fibre-free implement such as a cocktail stick (a cotton bud can be used but there is a risk of leaving fibres behind). Always refer to manufacturer's instructions. If in doubt leave it to an experienced pen repairer.
