Its stiff, non-bleeding formula ensures superior sealing and lubrication across a wide temperature range, protecting delicate pen components without any harmful additives. Trusted by pen enthusiasts for smooth piston action and reliable o-ring lubrication, it’s the essential upgrade for any serious pen collector or repairer. ## Description MicroLubrol StyloSeal (TM) is a very high quality, very pure 100% silicone grease that offers superior sealing and lubrication performance in fountain and eyedropper pen applications. MicroLubrol StyloSeal is a STIFF, non sagging and non melting silicone sealing and lubricating grease that maintains its consistency at all temperatures. It is a stiffer, more viscous grease with lower silicone oil content than most standard silicone greases, which makes it a very stable product and prevents oil "bleed." "Bleed" of the base oil from the grease is a problem with many ordinary silicone greases. MicroLubrol StyloSeal (TM) contains a high quality, high viscosity 100% pure silicone oil base that provides superb long term usability without bleed, gumming, separation, hardening or degradation of any kind of the grease. MicroLubrol StyloSeal (TM) 100% Pure Silicone Grease has been tested by pen enthusiasts and is the perfect grease for eyedropper conversions of cartridge type fountain pens as well as for any sealing applications in any type of fountain or eyedropper pen. MicroLubrol StyloSeal (TM) is available in a MEDIUM consistency and in a HEAVY consistency. Both the MEDIUM and the HEAVY grades provide excellent sealing and lubrication on pen applications. You can get a heavier or a lighter grade depending on your application. If you want a very stiff, thicker grease for heavier duty sealing such as in eyedropper pen conversions, try MicroLubrol StyloSeal HEAVY grade. If you prefer a slightly less viscous, less stiff silicone grease for less demanding sealing applications such as piston fillers or for simple o-ring lubrication, then try MicroLubrol StyloSeal MEDIUM grade. Review: thicker silicone gel - great for seal and lubrication of fountain pen piston after thorough wash Review: Did my first pen repair - My Omas Milord Arco Celluloid fountain pen stopped drawing ink. After looking at several YouTube videos I decided to take it apart and repair it myself. It was a little difficult to remove the section, but I finally got it off. The plunger rod had become disconnected from the knob. I coated all of the connecting parts with a small amount of the silicon grease, and the piston rod, and reassembled the pen, making sure that the knob was attached to piston rod. Everything went back together smoothly. I filled the pen and it had no leaks. This product works as advertised. ## Features - 100% pure silicone base. Inert and nonreactive.
