Single-handle vessel faucet

The Kingston Brass NS8420DKL Water Onyx is a single-handle vessel sink faucet built from high-quality brass. Its cylindrical body and black nickel finish suit modern bathrooms. The deck-plate mounting covers a single-hole cut-out for a clean installation.

Washerless cartridge and tested finish

A durable washerless cartridge controls flow and temperature without rubber washers that wear out. The black nickel coating meets ASTM B117 and ASTM B368 salt-spray and corrosion requirements. Normal daily use runs quietly at household pressure.

Brass build and anti-slide handle

Solid brass construction resists deformation and leakage over time. The DKL handle includes a neoprene insert that prevents slipping when hands are wet. A matching brass pop-up drain assembly is included for the sink waste.

Questions about this item

How do I install the single-hole mono block with the included deck plate, and what step is often missed?

Mount the faucet through the single hole, place the deck plate underneath, and secure it with the hardware; the step often missed is tightening the mounting nut evenly so the brass body sits flush without wobble.

Which part will need replacement first under normal use?

The washerless cartridge is the wear item; it can be swapped out without replacing the entire brass body.

At what point does the Black Nickel finish reach its corrosion-test limit?

The finish meets ASTM B117 and ASTM B368, so sustained salt-spray exposure beyond those test thresholds is where degradation would first appear.
