KEZE Waterproof Water Grade Silicone Lubricant Grease for Valve Sealant Faucet O Rings 1oz 1 Pack

Effecient, reasonably priced, and non-problematic.

This plumber’s grease works well for sealing and lubricating valves and fittings. It applies smoothly, creates a reliable seal, and holds up over time without washing away easily. For plumbing tasks, it does exactly what it should. The only drawback is the smell—it has a strange odor that lingers a bit when you first use it. It doesn’t affect performance, but it’s noticeable compared to other silicone-based lubricants. Overall, a solid and effective product, just with an off-putting scent.

Work as described. Applied to brake stopper pins, and pads seem moving smoothly.

I used this to lubricate the cam assembly of my e61 group head espresso machine. It's been 2 months so far and the lubrication is still effective despite the espresso machine being on 24/7. Highly recommend this lubricant for espresso machines.

Great for latches and key locks. Fixed a screen door latch when the door wasn’t closing on its own. A neglected deadbolt now works like new. Better than WD40.
