Decent Gasket removal tool & deep dive video
DECENT GASKET REMOVAL TOOL
We've designed our own group head gasket removal tool.
We tested lots of gasket removal tools, but found that:
- the ends of most were too thick to easily insert along the side wall of the gasket.
- Or…. they were too fragile and the tool tip bent under use.
What we liked best, was a professional dental tool.
So we contact a dental tools manufacturer, and tried all the ends they sold.
We then made our own tool, with the two ends we liked the best.

DEEP DIVE ABOUT GROUP HEAD GASKETS
Paul and I did a “brain dump” of everything we know about espresso gaskets, and what you might like to know too.
I know, I know, a 22 minute video about the espresso gasket is a bit hard to believe.
But yeah, it turns out, there are lots of things to say about this very humble part.
The gasket video isn't targeted specifically at Decent Espresso customers. It's really just everything we know about gaskets, that you might find useful to know too. http://decentespresso.com/gasket
AI Summary:
The video discusses gaskets, specifically those used in espresso machines, focusing on the different types of materials used (NBR rubber and silicone) and how to care for, maintain, and replace them. The key points of the video are outlined below:
Highlights:
- Types of Gaskets:
- NBR Rubber: Used in most traditional machines, more rigid and can wear out faster if over-tightened.
- Silicone: Softer and more flexible, which requires a bit more force to lock in, but is gentler on the machine.
- Common Issues with Gaskets:
- Over-tightening the gasket can cause premature aging, especially if done when the machine is hot.
- Leaving the portafilter locked too tightly overnight causes heat to degrade the gasket faster.
- Not cleaning the gasket properly can cause leaks due to trapped coffee grounds.
- Gasket Maintenance:
- It's important to clean the gasket regularly using a rag, toothbrush, or specialized tools.
- Dental tools or picks are recommended for detailed cleaning, but proper care must be taken to avoid damaging the gasket.
- Testing for Gasket Issues:
- A common test involves using a blind portafilter basket to check for leaks. If water drips during a flush, the gasket might be faulty.
- Reinstalling a Gasket:
- When replacing or cleaning the gasket, proper orientation is essential. The gasket has a curved side (camper) that must face inward.
- A blind basket is used to reseat the gasket to ensure a proper seal.
- Gasket Lifespan:
- Gaskets can last anywhere between 2-12 months depending on usage and care. Minimizing heat exposure by removing the portafilter after use helps extend its life.
- Gasket Fit and Adjustments:
- If the gasket is too tight or too loose, you can adjust the fit by selecting a thicker or thinner gasket.
- Some machines may have worn-down parts (like the bayonet), causing the portafilter to lock too far in or too loosely, which can be corrected with a gasket of different thickness.
- External Factors:
- Some portafilters with different designs may not fit perfectly, requiring adjustments to the gasket size for optimal sealing.
- Cafe Lot makes silicone gaskets in various colors and thicknesses, offering a more affordable option for replacing gaskets.
- Practical Tips:
- For ease, flipping the machine upside down while cleaning helps reach the group head more effectively.
- Regularly wipe the portafilter area to avoid coffee grounds getting trapped in the gasket, which can affect the seal.
Summary:
The video provides in-depth insights into espresso machine gaskets, explaining the differences between NBR rubber and silicone, their care and maintenance, how to replace and clean them, and how to troubleshoot common issues like leaks. It emphasizes that gaskets are an essential yet often overlooked component of espresso machines, and proper maintenance and handling can significantly extend their lifespan and improve performance.
