i WAS disappointed with this regulator`s performance. As my tests showed, the product was not able to withstand the high-pressure demands required for Industrial and Scientific applications. The pros about this product are that it is easy to install and use, but unfortunately this does not make up for the cons. The cons being that this regulator's lack of durability makes it unsuitable for demanding applications. I would advise those in need of a reliable regulator for their Industrial and Scientific needs to look for a more reputable brand. .
