You have had your Aeropress for a couple years and love it. The air pressure isn’t tight and the coffee is leaking through the rubber Time for new one right? Wrong!
There is a quick and easy fix Aeropress coffee and espresso maker. You do not have to go out and buy an entirely new unit. In a nutshell, what you need to do is buy a new rubber piece that goes on the end of the plunger.
More often than not, it is time to replace the plunger tip. Think of it as a gasket – any mechanic will tell you gaskets wear out. Here is an image of the part you need to purchase and change. Simply buy it, install it, and you have a revitalized Aeropress that will make coffee for years to come. There are, however, a few things you should know about the product in the process.
The Evolution Of The Aeropress Coffee And Espresso Maker
I did some extensive research on the lifespan of the Aeropress coffee maker. As per the manufacturer – the AeroPress coffee maker is warranted against defects in materials and workmanship for a period of one year from date of purchase from an authorized retailer. They advise you to keep your receipt so that if you have a problem with your AeroPress before one year has passed, you can prove when you purchased it and that you purchased it from an authorized retailer that sells genuine AeroPress coffee makers.
Virtually all of the pressure losses in the AeroPress occur as a result of the rubber plunger/gasket failure. Unfortunately, these failures generally occur at about the two-year mark. So you’re outside the warranty coverage period.
I began to wonder, is this designed obsolescence? Are they using inferior materials to try to get you to buy a new unit every couple years?
I discovered that the product has been constantly under development. The changes in development have occurred as the public has become aware of the potential dangers of plastics interacting with food and storage containers. These interactions can be especially worrisome when heat is involved. It accelerates interactions.
The company has listened to customer responses and in 2014 change the material from which the chamber and plunger are made from.
The plunger, from 2009 t0 2014 was made of medical grade thermoplastic elastomer that we buy from a supplier for medical syringes. The chemical name is styrene-ethylene-butadiene-styrene. It is made in the USA and is FDA and EU approved for use in contact with food. The AeroPress has always been free of phthalates and has been free of BPA since August of 2009.
In the summer of 2014, they switched to making the chamber and plunger out of polypropylene. This means that all of the AeroPress parts except the rubber-like seal are now made of polypropylene. That is all very nice, but our problem piece IS the rubber seal.
They made the change because tests indicated the polypropylene is more durable. What suffered during this change was the fact that the chamber is now less transparent and it is a little bit more difficult to see the coffee. The company thought it was a good trade-off for additional durability.
How to Replace The Plunger On The Aeropress Coffee And Espresso Maker
When it comes to figuring out how to replace the plunger tip, we have some good news for you in some bad news for you:
- The good news is that it’s a simple pressure fit – you just have to push it on.
- The bad news is – it’s a really tight fit and you might find that you’re doubting yourself about whether it will fit or not.
Okay, so let’s try to get a handle on this. There is no one, single, proper and effective way to get the rubber plunger tip on the plunger itself. I have hunted high and low, scouring YouTube, check out the manufacturer’s instruction book, in trolling forms looking for a single great answer I can pass on to you.
There just isn’t one. What I’d did discover were several different methods that have worked for different people. So I’ll list them out for you. Remember, the good news is you just need to find the one that works for you.
Finding the right technique is the hard part the actual plunger replacement takes about two seconds once it snaps firmly into place.
How To Get The Plunger Tip On
Method #1 – Several people have had success simply by heating the gasket up by letting it soak in very hot (not boiling) water for a minute or two. This seems to expand it, and “loosen” it up to make it go on a little easier.
Method #2 – Place the plunger tip flat on the counter. Holding the plunger at about a 45° angle work one small edge into it, just to get it started. Keeping the plunger held at an angle role the plunger around on the plunger tip you’re holding steady. An extra set of hands to hold the plunger tip firmly would probably help.
Method #3 – this method is risky. You risk damage to the parts. I kind of cringed when I heard it, but hey, desperate people do desperate things. Use a small flat bladed screwdriver to twist the opening and worked the plunger tip onto the plunger. If you’re desperate enough to try this please be very careful because you can tear the gasket tip.
