Its high viscosity, non-bleeding formula provides superior sealing and lubrication for piston seals, o-rings, and cartridge conversions, maintaining stability up to 500°F without additives that degrade plastics or rubbers. ## 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. ## Features - 100% pure silicone base. Inert and nonreactive. Compatible with all inks, polar and non-polar. - Sealing and lubrication of piston seal fountain pens. - Thread sealing and o-ring lubrication in cartridge pen eyedropper conversion applications. - O-ring lubrication in watches and water-resistant equipment. - NO additives such as lithium soap thickener. NO petroleum distillates or petroleum by-products which can degrade plastics and rubbers. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B01HNNDYM2 | | Best Sellers Rank | #314,122 in Automotive (See Top 100 in Automotive) #198 in Automotive Lithium Greases | | Brand Name | MicroLubrol | | Compatible Material | Plastic | | Container Type | Can, Cartridge | | Customer Reviews | 4.8 4.8 out of 5 stars (36) 4.8 out of 5 stars | | Item Form | Grease | | Item Weight | 0.27 g | | Manufacturer | MicroLubrol | | Material | Silicone | | Model Number | StyloSeal Heavy | | Number Of Items | 1 | | Number Of Packs | 1 | | Part Number | MLSSH1 | | Recommended Uses For Product | Lubricant | | Sae J300 Viscosity Grade | 75W-140 | | Specific Uses For Product | Fountain Eyedropper Pen Lubrication | | Upc | 036663592774 | | Upper Temperature Rating | 500 °F | | Viscosity | High Viscosity | | Viscosity Level | High | ## Product Details - **Brand:** MicroLubrol - **Item Weight:** 0.01 Ounces - **Material:** Silicone - **Package Information:** Can, Cartridge - **Recommended Uses For Product:** Lubricant ## Images ![StyloSeal Heavy Consistency (High Stiffness) 100% Pure Silicone Sealant & Lubricant Grease for Fountain and Eyedropper Pen Applications - Image 1](https://m.media-amazon.com/images/I/51TTRovuaSL.jpg) ## Questions & Answers **Q: What is the quantity in the container?** A: The container has no quantity marked, but setting it next to a 4 oz. tube, it looks like maybe 1 oz. **Q: Just how viscous is this grease?

Mildly viscous ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy fix for many fountain pen leaks *by on Reviewed in the United States May 15, 2024* I had at least a couple of fountain pens (the ones I hadn't lost track of) which I hadn't been using because they leaked like sieves. I kept looking up, or trying to look up ways to seat the converters so they'd stop leaking, and never managing to get them back into working order. I finally ordered this, applied a scant amount to the converters, and have had no more problems with leaks. It was a very simple fix, and would have been a very good investment even if I'd only had one leaky pen.Thank you for reading my review. I hope you found it helpful. ### ⭐⭐⭐⭐⭐ good for retractable pens with a bad seal *by on Reviewed in the United States October 30, 2025* I put this in my jinhao 10 for a better seal and so far it hasn't dried out yet. ### ⭐⭐⭐⭐⭐ thicker silicone gel *by on Reviewed in the United States November 12, 2025* great for seal and lubrication of fountain pen piston after thorough wash --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/30866621-styloseal-heavy-consistency-high-stiffness-100-pure-silicone-sealant-lubricant](https://www.desertcart.tn/products/30866621-styloseal-heavy-consistency-high-stiffness-100-pure-silicone-sealant-lubricant) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-18*
