Replacement spray core (Sprühkern) for K2–K7 lance Key benefits Restores original spray performance: replaces the worn or damaged spray core in the lance to recover correct spray pattern and pressure. Durable and corrosion-resistant: solid copper construction resists corrosion and wear for longer service life. High temperature tolerance: precision-machined component withstands elevated temperatures without deformation, maintaining consistent operation. What it does Designed to directly replace the original Sprühkern inside the lance for models K2, K3, K4, K5, K6, and K7. Maintains nozzle alignment and spray stability to reduce vibration and uneven spray. Compatibility Direct fit for lance models K2, K3, K4, K5, K6, K7 (replacement for the original spray core). Intended as a component-level replacement; verify lance model before installation. Material and construction Made from copper for good thermal conductivity, corrosion resistance, and mechanical durability. Fine machining/engraving ensures precise tolerances and reliable sealing with the lance assembly. Performance advantages Reliable under high-temperature conditions, preventing warping and preserving spray geometry. Corrosion resistance reduces the risk of clogging or deterioration in contact with water and cleaning agents. Longer service life compared with lower-grade materials, reducing the frequency of replacements. Typical applications Home pressure washing: replace a worn spray core to restore cleaning efficiency on cars, drives, and siding. Workshop maintenance: maintain stable spray performance for equipment cleaning and preparation tasks. Light commercial use: suitable for restoring lance performance in rental or fleet pressure washer units that use K2–K7 lances. Notes for users Confirm that the lance is a K2–K7 model before purchasing. Install as a one-for-one replacement of the original Sprühkern; check seals and threads for wear during replacement. Regular inspection and proper filtration of inlet water will extend the life of the spray core.
