Thank you for your question. You can cap off the valve end so that you don't have to use the sprayer for this faucet. To know what cap to use for your Delta Windemere Kitchen 21996LF faucet, you will want to look at the back of the faucet for the supplier code. If your supplier code says 413763-A and has a square end, you will need cap part number RP60295. If your supplier code says 413763 (without an 'A'), you will need cap part number RP40301.
