O-ring set SCHAERER Spare Parts 1340051997

O-rings form a flexible seal between moving or fixed parts in coffee machines, preventing leaks of water, steam or coffee oils. They are made of an elastic material that compresses when the parts are tightened, filling microscopic gaps and blocking the passage of liquids or gases. Over time, heat, pressure and cleaning chemicals cause the material to harden or crack, so the seal loses its effectiveness and must be replaced to keep the machine operating without drips or pressure loss.

This SCHAERER spare O-ring set is designed to restore the original seal in the manufacturer's coffee equipment. The operator removes the worn ring, cleans the groove, fits the new ring into place, and reassembles the joint. The elastic material regains its shape under compression, recreating the barrier that keeps water and steam where they belong.

The set contains the exact dimensions and material specified by SCHAERER for its machines, ensuring compatibility and a reliable seal. No tools beyond basic hand tools are required for replacement, and the process takes only a few minutes once the machine is cooled and isolated from the supply.

Use the set only on the makes of equipment listed by SCHAERER for this article number to avoid mismatched sizes or materials that could lead to leaks or damage.
