Kingston Brass CC471 Vintage Double Offset Bath Supply

Kingston Brass CC471 Bath Supply

Check Price on Amazon

Built from solid brass, the Kingston Brass CC471 is designed for reliability in bath setups where a longer reach is beneficial. Its 25-inch length and 2-3/4-inch width ensure compatibility with a range of basin configurations and deck-mount installations. The 2-3/8-inch bottom flange provides a solid seal against the sink deck, reducing the risk of leaks. Installation is straightforward for DIY enthusiasts with basic plumbing know-how. This model emphasizes durability and a classic look that works well with traditional bathroom decor, while providing dependable performance for daily use.

Key considerations include its bulkier footprint relative to compact modern lines, which may influence choice in tighter vanity spaces. The polished chrome finish offers a bright, timeless aesthetic that resists tarnish, though customers should verify compatibility with their existing supply lines and escutcheons. For those upgrading an older bathroom or replacing a worn-out supply, CC471 offers a robust, long-term solution with straightforward maintenance.

The EZ-Fluid supply lines deliver versatile, durable connections for kitchen and bathroom fixtures. Each 20-inch line features 1/2″ female iron pipe threads on one end and 3/8″ compression fittings on the other, with stainless steel braided construction for flexibility and strength. Brass nuts and cUPC/NSF-certified lead-free materials provide peace of mind for household plumbing. Available in multiple lengths, these lines are suitable for a range of sink configurations and faucet setups, reducing the need for extra adapters.

Considerations include ensuring your faucet shank sizes match the 1/2″ FIP and 3/8″ compression ends. The stainless braid helps prevent kinking and abrasion, extending the line life in high-use areas. While universal, some installations may require longer or shorter lengths depending on cabinet layout and supply shutoffs. EZ-Fluid lines strike a balance between affordability and dependable performance for everyday plumbing tasks.

KOHLER’s Genuine Part line focuses on compatibility and reliability for fixture repairs. This product category centers on cartridge assemblies and repair components designed to fit KOHLER fixtures, helping maintain performance and prevent leaks over time. The emphasis is on authentic parts that preserve warranty protections and ensure consistent operation across KOHLER systems. This is particularly valuable for homeowners with KOHLER fixtures seeking replacement components rather than full unit replacement.

When evaluating, consider the specific model compatibility and the availability of replacement cartridges, seals, and stems. Using genuine parts can streamline repairs and deliver predictable results, though alternative third-party parts may be cheaper. For those maintaining a KOHLER bathroom or kitchen, these repair supplies provide a trusted option to restore optimal function without major renovations.

The brushed or polished finishes coordinate with other Kingston Brass fixtures for a unified look.

Key considerations include ensuring the included supplies align with your sink’s configuration, such as deck thickness and vanity space. The kit’s solid brass components are durable, though compatibility with non-Kingston Brass fixtures should be reviewed.

The Kingston Brass CC462 offset bath supply in polished brass delivers a compact alternative to longer models. With overall dimensions of 22-9/16 inches in length and 3-7/16 inches in width, it fits bathrooms where space is more constrained yet still requires a rigid, dependable supply line. Crafted from solid brass, this unit emphasizes durability and a classic aesthetic suitable for traditional bath designs. The 2-3/8-inch bottom flange/escutcheon adds a clean, finished look at the deck level and helps seal against leaks.

When selecting, consider your vanity layout and whether a shorter offset better matches the faucet spacing and drain configuration. The polished brass finish provides a warm tone that pairs well with antique or vintage fixtures, while maintaining resistance to corrosion and wear. For bathrooms needing a reliable, aesthetically cohesive supply option without extending deep into cabinetry, CC462 offers a solid balance of form and function.

Buying Guide

  • Material durability: Solid brass components resist corrosion and wear, offering long-term reliability in high-use bathrooms.
  • Fit and compatibility: Verify thread sizes (1/2″ FIP, 3/8″ compression, or other) and whether the product matches your faucet, drain, and valve configurations.
  • Length and space: Measure the distance from the valve to the faucet deck to ensure an appropriate reach for offset supplies and trim kits.
  • Finish and style: Choose finishes (polished chrome, brass, brushed brass) that complement existing fixtures and decor.
  • Installation considerations: Some kits include all necessary components for a single install, while others require separate purchases for compatibility and finishes.
  • Code and standards: Look for listings such as cUPC/NSF for supply lines to ensure lead-free materials and compliance with plumbing codes.
  • Repair versus replacement: For existing brands like KOHLER or Kingston Brass, genuine parts may preserve warranties and simplify maintenance; evaluate whether a full kit or individual component is needed.
  • Maintenance and care: Metal finishes can patina over time; regular cleaning with non-abrasive products helps maintain appearance and function.
  • Budget versus value: While premium kits and solid brass parts cost more upfront, they typically offer longer service life and fewer leaks, reducing long-term costs.
  • Warranty and support: Consider supplier warranties and availability of replacement parts when planning upgrades or replacements.
