Upgrade your espresso machine’s performance with the Caffewerks 7.5mm Silicone Group Gasket, engineered specifically for E61-style brew groups. Unlike traditional rubber seals, this durable, food-grade silicone gasket offers a longer lifespan and improved seal retention, helping reduce maintenance downtime and ensure consistent espresso extractions. A must-have for baristas and technicians, this gasket is ideal for routine service or precision-tuning the group head fit, particularly when portafilter handle alignment or sealing is inconsistent. Features: 7.5mm Thickness: Optimised for a tight seal in E61 group heads High-Grade Silicone: Odourless, food-safe, and more durable than rubber Temperature-Resistant: Holds shape and elasticity under repeated high-heat cycles Improved Seal Integrity: Helps eliminate leaks and improve brew consistency Easier to Remove: Less prone to hardening or cracking over time Colour: Red/orange silicone for easy visual inspection Why Choose Silicone Over Rubber? Traditional rubber gaskets can deteriorate faster, causing leaks and requiring more effort to engage the portafilter. Our silicone gaskets are a superior alternative — more durable, heat-resistant, and easier to use. They ensure smoother operation and consistent brewing quality over time.
