The DELTA FAUCET RP50391 is a replacement gasket and baseplate assembly designed for single-handle pull-out faucets. This component provides the sealing interface between the faucet body and the sink deck, preventing water intrusion and ensuring a stable, leak-free mounting surface. It is a direct OEM-style replacement part intended for installation by licensed plumbers or qualified service technicians performing faucet repairs or fixture replacements in residential settings.
This gasket and baseplate assembly is suited for single-handle pull-out kitchen or laundry faucet configurations. It is typically installed during faucet repair when the original gasket has degraded, cracked, or lost its seal, or when a full faucet rebuild is underway. The part is appropriate for use in residential sink installations where maintaining a watertight deck mount is required.
Designed as an OEM-style replacement gasket and baseplate for DELTA FAUCET single-handle pull-out faucet models. Consult the original faucet documentation or DELTA FAUCET technical resources to confirm fitment for your specific model before installation.
Installation should be performed by a licensed plumber or qualified technician. Shut off the water supply valves under the sink and relieve line pressure before disassembling the faucet. Follow local plumbing codes, including applicable IPC requirements, when servicing or replacing faucet components. Avoid overtightening the mounting hardware, as this can distort the gasket and compromise the deck seal.
