It restores proper flow control and shutoff function to the cold water handle of Roman tub trim sets. This cartridge is a direct OEM-style replacement designed for plumbing service professionals who need a reliable, specification-matched component to complete a valve repair without replacing the entire trim assembly. Correct cartridge identification is essential before ordering — confirm the cold-side designation matches the existing valve body.\u003c\/p\u003e\u003cp\u003eThis cartridge is intended for Roman tub faucet applications in residential settings. Roman tub faucets are deck-mounted or deck-trim configurations commonly installed on freestanding soaking tubs and platform-style tub surrounds. The NB 1-003 addresses the cold water supply side of the valve assembly, making it the appropriate part when the cold handle is the source of dripping, rough operation, or loss of shutoff function.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCold-side cartridge replaces a worn or failing valve stem in Newport Brass Roman tub faucets\u003c\/li\u003e\n\u003cli\u003eOEM-style fitment for specification-matched performance\u003c\/li\u003e\n\u003cli\u003eRestores smooth handle operation and reliable shutoff\u003c\/li\u003e\n\u003cli\u003eTargeted cold-side designation prevents misapplication with hot-side cartridges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style cold-side replacement cartridge for Newport Brass Roman tub faucet valve assemblies.
