The VALUE COLLECTION K4079011 is a Kalrez O-ring with a round cross section, sized at 0.313 inches inside diameter, 0.438 inches outside diameter, and 0.0625 inches thick. Kalrez is a perfluoroelastomer compound known for exceptional resistance to aggressive chemicals, fuels, solvents, and high temperatures. This O-ring carries a working temperature range of 0 degrees F to 500 degrees F, making it well suited for demanding sealing applications in process equipment, chemical handling systems, and industrial fluid connections. It is installed by plumbers, pipefitters, millwrights, and industrial maintenance technicians where standard elastomers would fail.
This O-ring is used in static and dynamic sealing applications across chemical processing, semiconductor fabrication, oil and gas, pharmaceutical, and industrial HVAC environments. The Dash 011 designation corresponds to a standard AS568 O-ring size, allowing straightforward cross-reference to groove dimensions. Its high-temperature and broad chemical resistance make it a preferred choice when Buna-N, EPDM, or silicone compounds are not compatible with the process fluid or operating conditions.
Designed as an OEM-style replacement or maintenance seal for equipment requiring an AS568 Dash 011 O-ring in Kalrez material, including pumps, valves, fittings, and fluid system components where high chemical resistance is required.
Installation is typically performed by licensed plumbers, pipefitters, or qualified industrial maintenance technicians. Shut down and depressurize the system completely before removing or installing any O-ring seal. Inspect the groove for nicks, burrs, or corrosion before seating the new O-ring, and avoid using sharp tools that could nick the sealing surface. Kalrez O-rings should not be lubricated with petroleum-based greases unless confirmed compatible with the compound.
