“Moving to a drip and converted to natives for less water needs. Used these to cap 20" stationary copper risers that had spray heads, and cap in ground pro spray pressure riser spray nozzles. Worked perfectly and very simple. Some needed Teflon to keep from dripping, so I would recommend just using Teflon with all of them when you change them out. Also would recommend these over the caps because the pressure riser will still work , which makes it easy to locate sprinklers if needed in the future.”
