Chicago Faucets 898-012KJKRCF
The Chicago Faucets 898-012KJKRCF is a commercial-grade, 3/16-inch offset eccentric inlet supply arm engineered as a genuine direct OEM replacement solution for wall-mounted service sink faucets. This technical plumbing component functions as an essential mechanical adapter, allowing facilities maintenance teams to fine-tune alignment between incoming building supply pipes and the fixed 8-inch valve body of a master service faucet. In grueling commercial environments—such as school janitorial closets, municipal maintenance hubs, airport utility bays, and healthcare sanitation facilities—rough-in water pipes behind structural walls are frequently misaligned, uneven, or shifted over time. By incorporating an intentional 3/16-inch offset configuration, this adjustable arm can be rotated during installation to correct minor dimensional discrepancies, providing a perfectly level and centered mount without the need for expensive, invasive wall demolition.
Constructed from heavy-duty solid cast brass, this resilient hardware piece is built to withstand continuous water line pressure, physical vibration, and thermal expansion. It features a rugged rough chrome finish (RCF) specifically tailored for demanding utility applications where raw durability and resistance to harsh chemical cleanings are prioritized over decorative polished plating. Internally, the supply arm is equipped with a integrated mechanical check stop valve assembly. This vital safety and maintenance feature serves a dual purpose: it prevents cross-flow contamination between the hot and cold water networks, and it acts as a localized shut-off mechanism. By sealing the internal check stop, technicians can isolate the individual fixture to execute cartridge replacements or routine maintenance, eliminating disruptive building-wide water shutdowns. Standardizing on authentic Chicago Faucets factory original components ensures accurate thread configurations, eliminates the leakage risks associated with third-party generic alternatives, and preserves original system warranty protections.
