Dear Valued Home Depot Customer,We have reached out to the manufacturer and their answer is, Yes this item would work for this application
Yes, you can use this 3/4 in. x 9/16 in. black rubber stopper to winterize 3/4 inch irrigation tubing. The rubber material is lightweight, durable, and designed to provide a secure watertight seal, which is ideal for preventing water from entering the tubing and freezing during the winter months. Here are the steps to use the rubber stopper for winterizing your irrigation tubing: 1. **Cut the Stopper (if necessary):** If the stopper needs to be adjusted to fit your tubing perfectly, you can cut it to the exact length required. 2. **Insert the Stopper:** Push the rubber stopper into the end of the 3/4 inch irrigation tubing until it fits snugly. 3. **Ensure a Tight Seal:** Make sure the stopper is fully inserted and provides a tight seal to prevent any water from entering the tubing. By following these steps, you can effectively use the rubber stopper to winterize your irrigation tubing and protect it from potential damage caused by freezing temperatures.

No, not in the bare open pipe. You'd need a rubber stopper that's 3/4" near the middle, so enough remains to remove it. All pipe sizes and fitting are nominal, so measure the inside diameter to be sure.
I cannot imagine they would not be ... but I am not an expert on food quality rubber so don't take my work for it. I can tell you they do not work well as a substitute for mushrooms in Chicken Tetrazzini. Actually that was kind of a disaster.
These are essentially laboratory-type stoppers. Run them through the dishwasher one time to be totally sanitary...or wash by hand.
The rubber stopper is designed for fastener and hardware uses. These are not food safe.

The picture shows the 2 diameters...A good estimate (from the picture) appears to be about 1 1/2 inches tall. I no longer have the stopper, so unable to measure it directly.
This rubber stopper is about 24-25mm tall.
