O-ring LF L1186846

An O-ring creates a tight seal between two mating surfaces in a fluid or gas system. In coffee and vending machines, it prevents leaks of water, steam or milk at joints and valves. Silicone is chosen for its flexibility across temperature changes and its resistance to the oils and acids found in coffee and dairy products. The ring sits in a groove; when the parts are assembled, the groove compresses the ring, filling any gaps and blocking the path of the liquid or vapour.

To replace the O-ring, the operator first isolates the machine from the water supply and electrical circuit. The faulty ring is removed from its groove with a non-metallic tool to avoid scratching the metal surfaces. The new ring is placed into the groove, ensuring it lies flat and is not twisted. The mating parts are then reassembled and tightened to the manufacturer's torque setting. Once the water and power are restored, the machine is tested for leaks under normal operating pressure.

This O-ring is made of red silicone. The thickness of 1.78 mm and internal diameter of 2.90 mm match the groove dimensions in the listed Saeco models, ensuring a precise fit without over-compression or slack.

The ring fits the following Saeco equipment: coffee machines SAECO CAPPUCCINA, MODULAR, MODULAR FAST FOOD and MODULAR UL; vending machines SAECO IDEA CAPPUCCINO 9 g and PR IDEA CAPPUCCINO; superautomatic coffee machines SAECO IDEA, IDEA COFFEE 3 PROD 9G and IDEA UL.
