Why Silicone Gaskets Are the Smart Upgrade for Your Espresso Machine?

by Neringa Pranskevičienė

If you're serious about making great espresso at home, you've likely upgraded your grinder, dialed in your shot, and maybe even splurged on a better tamper. But there's one small part most home baristas overlook - the group head gasket.

Traditionally made from rubber, this essential sealing ring sits inside the group head and ensures a tight seal between the portafilter and the espresso machine. But over time, rubber gaskets degrade and that can hurt your machine, your coffee, and your sanity.

Enter the upgrade you didn’t know you needed: silicone gaskets.

At VeryBarista.com, we carry high-quality Cafelat silicone gaskets for popular machines like E61, Gaggia Classic, Breville, Sage, Rancilio, and La Marzocco. In this post, we’ll explain why silicone is better than rubber, how to know it’s time to replace your gasket, and what benefits you’ll enjoy with this simple but powerful upgrade.

Why Replace Your Rubber Gasket?

Rubber gaskets are the standard in most espresso machines, but they come with some serious downsides:

  • They bake hard over time: With constant exposure to high heat and pressure, rubber gaskets harden, crack, and lose elasticity.
  • They become nearly impossible to remove: Old rubber gaskets can feel "baked in," often requiring sharp tools and tons of effort to replace.
  • They can affect the taste of your coffee: Ever notice a burnt rubber smell when pulling a shot? That’s not normal and it’s definitely not ideal.
  • They leave behind black soot and residue: As rubber breaks down, it sheds particles that can make their way into your group head, portafilter, and eventually, your espresso.

Why Silicone Gaskets Are Better?

Cafelat silicone gaskets solve all of these problems and more. Here’s why they’re quickly becoming the gold standard among pros and home baristas alike:

1. Odorless & Tasteless

Silicone doesn’t carry the burnt rubber smell or affect the flavor of your espresso. That means a cleaner, purer shot every time.

2. Food-Safe & Non-Toxic

Made from FDA-approved food-grade silicone, these gaskets are safe, durable, and non-reactive even under extreme heat and pressure.

3. Softer Material = Easier to Install and Remove

Unlike rubber, silicone gaskets maintain their flexibility. They don’t bake rock hard over time, making installation and replacement simple - even after months or years of use.

4. Better Seal Without Excessive Force

Cafelat silicone gaskets are engineered to match the compression strength of rubber while offering a more forgiving seal. That means less wear on your portafilter lugs and a more consistent pressure profile.

5. Longer Lasting

Thanks to superior material properties, silicone gaskets generally last longer than rubber - saving you time and money in the long run.

How to Know It’s Time to Replace Your Gasket?

Not sure if your gasket needs replacing? Here are the signs:

  • You notice water leaking around the portafilter
  • Your shots are inconsistent or channeling
  • It’s extremely difficult to lock in your portafilter
  • You see visible cracking or flaking on the gasket
  • A burnt smell appears during or after brewing
  • If any of these sound familiar, your gasket is overdue for a change - and it’s the perfect time to upgrade to silicone.

Small Upgrade, Big Difference

Swapping your old rubber gasket for a Cafelat silicone gasket might be one of the easiest espresso machine upgrades you’ll ever make but the benefits are huge. Cleaner coffee, better machine protection, easier maintenance, and a longer lifespan. 

Still not convinced? Here are few more angles that can help us persuade you to make the switch:

Save Your Portafilter. Rubber gaskets often require you to over-torque the portafilter to get a good seal. This can wear down the lugs on your portafilter. Silicone provides a solid seal with less pressure, protecting your gear over time.

Easier Maintenance for Less Mess. Silicone doesn’t leave behind black residue or flakes that need to be scrubbed out - less grime, more shine.

Ideal for Home Baristas with Arthritis or Hand Fatigue. Silicone compresses more easily, it’s a huge help for users with grip or mobility issues.

Aesthetic Touch. Available in different colors for some models, silicone gaskets can add a pop of personality under the hood especially if you love creating visual content with your machine.
