Chicago Faucets 897-012JKRCF

The Chicago Faucets 897-012JKRCF is a genuine, commercial-grade 3/16-inch offset inlet supply arm assembly designed as a direct OEM factory replacement part for heavy-duty service sink fittings. This specialized plumbing component serves as an adjustable mechanical bridge between the structural building water supply and the fixed inputs of the faucet body. In high-traffic service areas—such as school janitorial closets, corporate maintenance bays, airport utility stations, and healthcare facilities—rough-in wall pipes rarely align perfectly to exact center-to-center measurements. By incorporating a precise 3/16-inch offset geometry, this supply arm can be rotated during installation to accommodate slight piping deviations, ensuring an exact physical alignment for adjustable 7-5/8 inch to 8-3/8 inch wall-mounted centers.

Constructed from industrial-grade solid cast brass, this heavy-duty hardware piece is precision-machined to ensure a secure, leak-proof seal that stands up to constant pressure, system thermal expansion, and mechanical vibration. It features an industrial rough chrome finish (RCF) engineered to deliver exceptional resistance to harsh oxidation, scale build-up, and corrosive chemical cleaning regimens standard in modern maintenance spaces. Engineered specifically for the iconic Chicago Faucets 897 Series wall-mounted manual service sink faucets, this factory-original assembly includes the vital structural washer required to lock in a flush connection against the valve body interface. Choosing authentic OEM replacement components guarantees perfect thread tolerances, shortens critical facilities maintenance downtime, and helps maintain the lifetime limited warranty protection of the master faucet assembly.
