Installing New Kitchen Faucet and Spout without Sprayer

We recently purchesed a new Kohler kitchen faucet and Spout. The valves/faucets (2) are seperate from the spout. There is a place to hook up the hot, cold and sprayer line to the bottom of the spout. We do not wish to hook up the sprayer as the hole in the sink is being used for a reverse osmosis water purifier.

Can I simply purchase a brass cap/fitting to cap off this connection?

Thank you

Yes you can.

cap

As long as it has a standard pipe thread you can. Some of the new Delta faucets are coming with a snap connection that cannot be eliminated. You should also remove the spray diverter from the faucet to eliminate its restriction.

Thanks gentlemen.
