Pilots HQDow Corning Molykote 111 Oring/Valve Lubricant/Sealant, 1/2oz (Repackaged for Smaller Applications), Water Resistant Lubricant, Food Grade Lubricant, Dow 111

I use this as a slide lubricant for my French Horn. While there are slide lubricants marketed specifically for musical instruments, none of them compare to the refined quality of this product. It costs more but in the small metal container it becomes affordable and conveniently fits in the average musician's instrument case. For those that care about daily longterm exposure to various chemicals, you should avoid most of the music instrument lubricants currently on the market and instead go with this product which can be used on food processing machinery.

Great product - works well with espresso maker seals

I recently replaced the gaskets between the lever and group head on my rocket espresso so bought this lubricant based on a recommendation from an espresso tech. It works great. I didn't realize how much the lube was needed since I've owned the machine for almost 13 years and it is used daily. I guess the deterioration of the original lube was so slow, I didn't notice how much more pressure I had to keep applying over time to lift the lever. I almost slammed the level when I first used it because there was almost no friction. This product is pretty expensive but the size of the purchase is more than enough for my lifetime use. Besides, spending that amount for a quality product on a $3k machine is a no brainer. One last comment. Some reviewers posted that their received product came in a plastic container. Mine did come in a small tin can as pictured in the product description.

This stuff works great!! Seller got it to us quick too!!

Perfect for any water filter housing or-ring, plumbing or-rings or scuba camera or lights or food contact appliance. Cheapest I could find online but might find almost 100% silicone scuba camera o-ring grease cheaper or at least a larger container size at your local shop.

A little does go a long way and even though this is a small tin, I suspect it'll easily last me years. Perfect for use when doing maintenance on my espresso machine to keep the group head gasket and shower screen lubed.

I always keep quality silicone grease on hand. I use it for all kinds of things: O-rings, rubber seals, gaskets, fountain pen piston/thread lube. This is a very high quality food grade, pharmaceutical grade, pure silicone grease. Can be used on SCUBA gear. This container would last most people many years. I bought Dow Corning Molykote 111 because it was recommended by a prominent fountain pen repair/restoration expert. A little goes a long way. DO NOT GET THIS ON A PEN'S NIB OR FEED OR ANY PLACE WHERE THE INK HAS TO FLOW TO THE TIP. On some piston filling pens I lube the rubber piston or the walls of the reservoir to keep the piston silky smooth. Good for threads on blind caps. I even disassemble most pen converters to do he same with them. Keeps the piston moving smoothly and does not get into the ink.If you have a TWSBI "AL" pen, DO NOT LUBE THE ALUMINUM PISTON THREAD WITH THIS GREASE. Aluminum threads require special grease. Email TWSBI customer service if you need lube for these parts. The lube TWSBI puts on these threads should last many years, do not remove the factory lube from the TWSBI AL pens aluminum parts.

Like all vortech pumps the porcelain shaft broke. Made my own with shrink wrap wire sleeves and then grease them for easer install and removal. Also keep the new ones quieter. I also grease the ring on the protein skimmer every couple of month.
