Description

The DIT-S threaded diaphragm seal is designed for measuring corrosive, crystallizing, or particle-laden media. Its removable diaphragm allows quick cleaning when clogged, making it ideal for chemical processing, pharmaceutical equipment, and pipelines carrying viscous or solid-containing fluids. Available in sizes from 70 to 160 mm with male, female, and union-nut threaded connections, it can be built from 304/316L stainless steel, Hastelloy, titanium, tantalum, Monel, and other corrosion-resistant materials. Compatible with both pressure gauges and transmitters, the DIT-S is a durable and easy-maintenance solution for demanding industrial applications.
