Review on 💎 Beryllium Diaphragm with Lower Movement Socket by Joel Young

Purchased to measure a recently installed natural gas line. The product was easy to use, easy to read and worked great taking the same readings previously taken by another tool the plumber was using. Worth the money for its durability (it's a solid piece of metal) and ease of use. Just a reminder to double check the diameter to make sure it matches the end of the pipes/fittings.
