Single Hole Bathroom Faucet CZ355202

Single Hole Bathroom Faucet CZ355202: Technical Specifications

The Single Hole Bathroom Faucet CZ355202 represents FaucetTaps engineering excellence, combining precision manufacturing with premium materials. Each unit undergoes a rigorous 12-point quality inspection including pressure testing at 150 PSI, finish adhesion testing, and 50,000-cycle cartridge endurance verification before leaving our Guangdong facility. This commitment to quality ensures every faucet delivers consistent performance across decades of daily use.

Materials & Engineering

Constructed from lead-free DZR brass (Dezincification Resistant) with a minimum 58% copper content, this faucet exceeds NSF/ANSI 61 standards for drinking water safety. The body undergoes precision CNC machining to tolerances of ±0.05mm, followed by multi-stage polishing to achieve a flawless surface. Internal waterways incorporate antimicrobial copper alloy linings that inhibit bacterial growth. Every seal and O-ring is food-grade EPDM rubber rated for temperatures from -40°F to 250°F, ensuring leak-free performance in extreme conditions.

Cartridge System

At the heart of this faucet is a premium ceramic disc cartridge manufactured by Kerox or Sedal — industry leaders in flow control technology. The cartridge features 25mm ceramic discs with diamond-polished surfaces that create a watertight seal without requiring excessive handle force. Rated for 500,000+ open/close cycles (equivalent to 45+ years of daily use), it eliminates the drip and handle stiffness common in inferior faucets. The hot water limit stop is factory-calibrated but adjustable, providing scald protection without sacrificing temperature range.

Finish Technology

Unlike conventional electroplating that applies a surface coating measured in microns, our PVD (Physical Vapor Deposition) process bonds the finish at the atomic level in a vacuum chamber. Titanium nitride or zirconium nitride particles are vaporized and deposited onto the brass surface, creating a finish layer 5-7 microns thick with hardness exceeding HV2500 — comparable to sapphire. This molecular bond means the finish cannot peel, blister, or corrode. Accelerated weathering tests confirm color stability for 25+ years with zero measurable degradation. Available finishes include our signature colors developed through 18 months of R&D to match premium interior design palettes.

Installation & Certifications

All mounting hardware is included: solid brass mounting nut with nylon lock ring, reinforced rubber deck gasket, and flexible braided stainless steel supply lines with standard 3/8-inch compression fittings. The supply lines feature 304 stainless steel braiding over EPDM inner tubing with a 400 PSI burst rating — triple the typical residential water pressure. Compatible with countertops from 0.25 to 2.5 inches thickness. Single-hole and three-hole installation configurations are supported with the included optional deck plate. Flow rate is factory-set at 1.8 GPM to meet WaterSense certification requirements, with an easily removable aerator for cleaning or flow adjustment.
