Flat seal SCHAERER Spare Parts 068423

A flat seal in coffee equipment creates a pressure-tight joint between metal surfaces. It sits between two rigid parts—typically the brew group and the water inlet or boiler—and compresses when the parts are tightened. The material flexes just enough to fill microscopic imperfections in the metal, stopping water or steam from escaping under pressure. Without a seal that matches the original specification, the machine loses pressure, leaks, or fails to reach the temperature needed for extraction.

The operator removes the worn seal with a plastic tool to avoid scratching the metal, cleans the seating surface with a dry cloth, and presses the new seal into the groove. Once the parts are reassembled and tightened, the seal is ready to hold pressure again. No adhesive or additional preparation is required.

This seal is manufactured to the exact dimensions and material grade used in SCHAERER coffee machines. It fits the designated grooves and maintains the correct compression when the parts are torqued to the manufacturer's specification.

The seal is a spare part for SCHAERER coffee equipment. It is listed in the catalogue under coffee-machine maintenance components.
