A plumbing professional needs to disconnect and cap a sprayer hose from a Delta Innoflex faucet system to install an RO faucet, but cannot identify the correct proprietary fitting or cap, and cannot drill a new hole due to space constraints.

There is no clear publicly available information on the type of fitting or cap needed to terminate a Delta Innoflex sprayer hose, and generic hardware store parts may not work, forcing the user to consider an expensive full faucet replacement.
