Value Collection K4079009 Kalrez O-ring Dash 009

Product Description

The VALUE COLLECTION K4079009 is a Kalrez O-ring with a round cross section, sized to the Dash 009 standard. It measures 0.219 inches inside diameter, 0.344 inches outside diameter, and 0.0625 inches thick. Kalrez is a perfluoroelastomer compound known for broad chemical resistance and a wide service temperature range, making this O-ring suitable for demanding sealing applications in chemical processing, semiconductor equipment, aerospace, and industrial fluid systems. Plumbers, pipefitters, and maintenance technicians working with aggressive media or elevated temperatures rely on this compound where standard nitrile or EPDM O-rings would degrade.

This O-ring is intended for static and dynamic sealing in systems that handle aggressive chemicals, solvents, fuels, or high-temperature fluids. Its Dash 009 sizing fits standardized grooves per AS568 O-ring dimensions. Typical install scenarios include pump seals, valve stems, instrumentation fittings, and fluid connectors where chemical compatibility and temperature stability are the primary design requirements. It is sold individually and is appropriate for both repair and original equipment assembly work.

Compatibility

Designed as a standard replacement or repair O-ring for any application requiring an AS568 Dash 009 dimensioned O-ring in Kalrez perfluoroelastomer material.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified maintenance technician. Always depressurize and drain the system before replacing seals, and confirm the groove dimensions match the Dash 009 standard before installation. Avoid using sharp tools that could nick or cut the O-ring during seating. Lubrication compatible with Kalrez compound and the process fluid should be used if required by the equipment manufacturer.
