If water, steam, or coffee leaks out of the filter while brewing then this part should be replaced. To replace this Gasket first remove the diffuser by removing the screw. Then, gently pull the old gasket off. Clean the area with a damp cloth. Install the new Gasket and reinstall the diffuser. Review: Works perfectly with Sage Barista Express - Fits my Sage Barista Express coffee machine perfectly. No leaks at all, have been using now for more than a couple of months. Review: Works for SMEG esspresso machine! - It's day one, but happy so far 😅. Works with our smeg. You get 2 gaskets for ~ 8£ next day delivery. Good deal. Edit (7.Dec): If using smeg portafiler all is fine. But! While trying to use the bottomless portafiler and tamping the coffee to about 15kg to make a proper espresso in a 18g basket it just doesn't hold up. I broke one seal gasket already. I don't know of the original would brake as well, but there is the possibility that's the case in order to avoid machine braking down. Well I think I need to invest in better coffee machine or gasket. Update 2 (10 Dec 2023): I strongly believe it was SMEG and not the gasket as I read about esspresso pressure and SMEG's pressure is too high at 15 bars. Perdect is 9 bars. I now press coffee button and press it again after first push in order to stop pressure building. Then I repeat this until I get perfect amount of water trough. It's an unnecessary hack but the coffee tastes much better with pressurless basket. ## Features - ☕【51mm Silicone Steam Ring For Espresso Machines】 Silicone Steam Ring compatible for Delonghi EC680/685/785/885/850/860,La Specialista EC9335M/EC9355M/EC9665M Coffee Maker etc. - ☕【Food Grade Silicone Material】 The Silicone Steam Ring of the coffee machine is made of high-quality silicone material, which is safe and durable, non-toxic, flexible and safe to use, more resistant to high temperature than ordinary rubber gaskets, and has a longer life. - ☕【Excellent Sealing Ability】 No BPA grouphead gasket replacement part soft silicone fits into grooves very easily, resulting in a tight and secure fit that seals to ensure no moisture escapes while minimizing necessary changes frequency. - ☕【Size】 The inner diameter of the brewing head gasket of the coffee machine is about 4.6cm/1.81inches and the outer diameter is 5.9cm/2.32inches inches.

The portafilter is held very firmly, and is much tighter than before, but still leaks. Using a new OEM seal works so I'd assume there are some differences in tolerance or sizes. ## Frequently Bought Together - NEOUZA 51mm Brewing Group Head Silicone Gasket 2Pcs O-Ring Compatible with Delonghi Dedica EC680/EC685,La Specialista EC9335M EC9355M EC9665M,Smeg ECF01 - De'Longhi EcoDecalk Descaler, Eco-Friendly Universal Descaling Solution for Coffee & Espresso Machines, 16.90 oz (5 uses) - EppoBrand 50mm Silicone Steam Gasket Ring Replacement for Delonghi Espresso Machine EC680 EC685 EC695 EC820 EC850 EC860 EC9335M EC9355M EC9665M --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/534556460-neouza-51mm-brewing-group-head-silicone-gasket-2pcs-o-ring](https://www.desertcart.jp/products/534556460-neouza-51mm-brewing-group-head-silicone-gasket-2pcs-o-ring) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-23*
