Value Collection K4079212 Kalrez O-ring Dash 212

Product Description

The VALUE COLLECTION K4079212 is a Kalrez O-ring with a round cross section, sized at 0.875 inches inside diameter, 1.125 inches outside diameter, and 0.125 inches thick. Kalrez is a perfluoroelastomer (FFKM) compound known for resistance to aggressive chemicals, high temperatures, and demanding process environments. This O-ring carries a Dash 212 designation, placing it within the standard AS568 sizing series. It is installed by plumbers, pipefitters, chemical process technicians, and industrial maintenance professionals where standard elastomers would degrade or fail.

This O-ring is suited for use in chemical processing equipment, fluid handling systems, pumps, valves, and fittings that operate under elevated temperatures or exposure to harsh chemicals. The Kalrez compound handles continuous service from 0 degrees F up to 500 degrees F, making it a reliable choice for high-temperature steam, aggressive solvents, and corrosive media where EPDM, Buna-N, or Viton compounds are not adequate. Sold individually.

Installation Notes

O-ring installation should be performed by a qualified plumber, pipefitter, or maintenance technician. Always depressurize and isolate the system before replacing any O-ring seal. Inspect the mating groove for damage, debris, or out-of-tolerance dimensions before installing the new ring. Avoid using sharp tools that could nick or cut the O-ring surface during installation, as surface damage will compromise the seal.
