Services OX/US/SI

Not just clean, but pure


Some fields of application for SERTO tube unions and valves are subject to high clean-liness requirements. For many years, SERTO has provided the options US (cleaned with ultrasound and not lubricated), OX (cleaned with ultrasound and lubricated for oxygen systems) and SI (cleaned with ultrasound and lubricated silicone-free for use in combination with paints and lacquers).

Above all in the semiconductor industry, for applications with pure oxygen, paints and lacquers, tube unions must be free of oil and grease. To ensure this, the components pass through a cleaning system and are assembled and individually packed in the SERTO ISO Class 8 clean room.
