LongDescription#@#NA#@@#Cleaning Instructions#@#Unplug equipment and clear the area. Remove old washers and O-rings from the Krowne 21-407 inlets. Inspect seals for cracks. Clean surfaces with mild detergent and a soft brush, then rinse and dry with a lint-free cloth. Install new Black Royal Series washers, ensuring proper alignment. Test for leaks under normal pressure and retighten fittings as needed. Regular cleaning prevents contamination, fires, higher bills, and equipment failure.#@@#Additional Info#@#Krowne 21-407 Black Royal Series inlet washers seal pre-rinse faucets, compatible with Krowne Royal Series and common plumbing fittings, weighing 0.5 pounds and easy for technicians to replace.#@@#General Info#@#Description #@#

#@@# Supply Inlet Seal#@#
Designed for direct replacement on supply inlets, these washers restore watertight connections and prevent leak-related downtime. Technicians will appreciate the predictable fit and immediate restoration of system pressure.
#@@# Durable Construction#@#
Manufactured to withstand repeated compression cycles, the washers resist deformation and maintain sealing integrity under continual use. Facilities can expect longer intervals between replacements compared with generic spare parts.
#@@# Black Finish#@#
The black color blends with matte and dark-plated fixtures and reduces visible staining from mineral deposits. Maintenance staff can standardize parts visually to speed identification during service.
#@@# Parts Compatibility#@#
These washers match the geometry and thickness used in common pre-rinse faucet inlet assemblies, ensuring proper seating and flow characteristics. Plumbers avoid adaptation work and maintain consistent hydraulic performance.
#@@# Compact Packaging#@#
Shipped in a small, manageable package, the parts minimize storage footprint and simplify stocking for service vehicles. Procurement teams gain predictable inventory turnover and reduce overstock risk.
#@@# Service-Oriented Supply#@#
Sourced from an established manufacturer founded in 1998, these washers integrate into B2B maintenance programs and supplier cycles. Facility managers can align ordering with preventative maintenance schedules and reduce emergency repairs.
