Restore the perfect seal in your espresso machine with the genuine O-RING 2,62X18,72 SILICONE 70ShA (Part # H.1.033). This small but critical component is essential for resolving common commercial espresso machine issues like a "leaking group head" or "espresso machine losing pressure." Engineered from high-grade 70 Shore A silicone, this O-ring offers superior thermal stability and chemical resistance compared to standard rubber, guaranteeing reliable performance under the constant high heat and pressure found in professional espresso brewing systems. When you notice your machine has a "bad seal" or "water dripping from portafilter," this OEM replacement ensures a tight, durable fit, minimizing downtime and maintaining the consistent pressure required for perfect extraction.

Specifically designed with a 2.62mm cross-section and an 18.72mm internal diameter, the H.1.033 O-ring meets strict OEM specifications, ensuring it performs exactly as intended in La Marzocco and compatible group assemblies. Utilizing a silicone compound allows this seal to withstand extreme temperature cycling without degrading or cracking—a common cause of a "steam wand leak" or "boiler connection failure" in older seals. Its usage is primarily found in critical fluid pathways and connections where high-temperature steam or water must be securely contained, offering a dependable fix when experiencing "inconsistent water flow." Investing in this quality silicone O-ring is the best way to maintain the longevity and optimal function of your valuable commercial espresso equipment.

Choosing this OEM O-RING 2,62X18,72 SILICONE 70ShA means opting for reliability and peace of mind. By proactively replacing worn seals—especially if you're asking "why is my espresso machine leaking inside?"—you prevent minor issues from escalating into major repairs. This item is an ideal solution for technicians and café owners performing routine "espresso machine preventative maintenance" or fixing specific problems associated with pressure loss. Ensure consistent extraction and prevent costly water damage by trusting this exact-fit, high-performance silicone seal from Kaldi.com, the definitive source for commercial espresso machine parts.
