Yes, lawn and garden sprayers generally have a standard thread size. Most commonly, the standard garden hose thread, known as GHT, is a 3/4-inch diameter straight (non-tapered) thread with a pitch of 11.5 threads per inch (TPI). However, it's important to consult the product specifications or manufacturer information to confirm the thread type, as there may be variations depending on the brand and model of the sprayer.
