On the top of the gauge there is a black plastic nipple that needs to be cut in order to regulate the pressure inside the gauge with the outside atmosphere. There should be a sticker on the gauge next to the nipple showing how to cut it as well.Sincerely,ScottHFS **Q: Mine need refilling. Is it oil or glycerine used to damp the reading?** A: Usually they are filled with glycerine. Don't forget to leave a small bubble at the top for thermal expansion (or you will have leaks). **Q: What's the difference between mpt and npt?** A: Npt is national pipe thread, a specific taper. Mpt is male pipe thread, fit is female pipe thread. **Q: Will this work for a vacuum pump running a dairy milker?** A: Hello,There should be no problem with that application.Sincerely,HFS ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect Gauge *by S***Y on Reviewed in the United States on July 24, 2022* Very well made and works like a champ... ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A Quality Gauge *by P***A on Reviewed in the United States on April 11, 2020* It appears to be a well made gauge. I can't speak to the accuracy since I do not have a suitable standard to base it against, but it does seem reasonable. The only reason for 4 stars for easy to read is because I feel a bit more fluid could have been put into the gauge that would reduce the size of the air bubble at the top, making it easier to read the most important segment. Some bubble has to be tolerated to allow for thermal expansion, Otherwise, it is a good gauge, especially for the money. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great Value! *by A***A on Reviewed in the United States on February 6, 2024* Exactly as expected.
