South Street Designs Replacement Plunger Seal, Compatible with AeroPress® Coffee and Espresso Maker

Fast delivery time, good value, easy to pop on, works perfectly. These are a tight fit inside the cylinder, but that just means that they will not leak, which is especially important if you are using the non-standard inverted method for steeping your AeroPress coffee. I have not been happy with how the originals and some of my replacements deteriorated over time, becoming hard and leaky or sticky and gooey, and therefore, unusable. Obviously, I have not had these replacements long enough to know how they will fare in that department. All I can tell you for the time being is that they don’t leak, don’t fall off, and did not cost a fortune. I can use my AeroPresses again, so yay.

Easy to swap out for the original. It felt a little stiff the first couple times pressing it through but that is likely because the old one was worn out. It worked perfectly the first time and did become a bit easier after a few times. Easy to remove for deep cleaning.

Worked as expected.

I have a really old press. Haven't used it in awhile, but got a new grinder and wanted to try out the press again. Pulled it down from the top shelf of the cupboard and the original plunger rubber was extremely sticky and looked to be deteriorating.Bought this as a replacement, works great. Only issue is that it's extremely tight in the plunger barrel. Works fine though, might have to just break it in some, or just be careful when pressing.

Unfortunately my original plunger got gunner and difficult to use so it needed to be replaced. Great fit and well made. Material feels durable and makes a great seal

My old original one started to break down for some reason (I think due to UV exposure) this one fits great and had no issues with it after several months of regular use

I have had my Aeropress since around 2013 and have gone through three "plunger seals". This one is, by far, the nicest one I've bought so far, and for the price appears to be a great buy. It seals better than the original (which I found to be too rubbery and in my experience would deform (shrink) too easily.) I hope it lasts, but so far, I have no idea of it's longevity.I also have little recourse but to trust (made in China) that the materials (siliconized rubber?) don't have any noxious or dangerous substances that would leach when used with very hot water. That is, I hope that any leaching is minimal and not worse that what coffee may provide!

The material this plunger disk is made of (silicone) is too sticky, and the disk is oversized. In combination, it's very difficult to press the plunger smoothly -- it sort of "jumps" from sticky spot to sticky spot -- and when pulling it back out, the plunger handle pulls out of the seal.All around, not a great replacement for the original. I've tried trimming around the edge a bit, but it didn't help.
