Solid allcopper spool for longlasting, leak performance Precisionmachined copper spool provides a reliable seal to prevent dripping and internal leakage. Copper resists corrosion for stable operation over time. Threedegree polishing treatment for smooth operation and wear resistance The threedegree polishing treatment reduces surface roughness and friction. Helps protect the part from wear and keeps movement smooth and consistent during use. Honeycomb foaming design for a soft, splash water stream The honeycomb foaming element aerates the water to produce a gentle, stable flow that reduces splashing. Delivers a comfortable, controlled stream for handwashing, dishwashing, and general faucet use. Practical benefits for everyday use Stops common faucet problems such as leaks and noisy, uneven flow. Improves user comfort at sinks by producing a soft, nonsplashing stream. Durable materials and surface treatment extend service life and reduce maintenance. Function and compatibility Functions as a faucet spool/valve component and flowshaping element. Intended for installation where a copper spool and aerating element are required; compatible with applications that use a replaceable spool and aerator assembly (check your fixture's service parts for fit). Use scenarios Kitchen sink: Provides a splash, soft stream for rinsing dishes and washing hands without drips or irregular flow. Bathroom sink: Delivers a gentle aerated flow that reduces splatter and improves comfort for daily handwashing and grooming. Maintenance and : Use as a durable replacement spool/aerator element to stop leaks and restore smooth faucet operation. Materials and performance summary Material: Allcopper spool. Surface treatment: Threedegree polishing treatment for antiwear and smooth operation. Flow element: Honeycomb foaming design for soft, nonsplashing water flow. If you are replacing a worn spool or upgrading an aerator element, this component focuses on leak prevention, durable movement, and a comfortable, splash stream without changing the basic function of your faucet.
