Ashcroft 100-101 Threaded Diaphragm Seals

The Ashcroft® 100 and 101 threaded diaphragm seals isolate pressure measuring instruments – pressure gauges, transmitters, and switches – from high-temperature, corrosive, or solids-laden process media that would otherwise damage or clog a direct instrument connection. The threaded inline body and field-replaceable diaphragm make the 100 and 101 well-suited for chemical processing, refining, paper and pulp, food and beverage, water and wastewater, and slurry service.

Standard construction is a 316L stainless steel top housing with a threaded-to-housing diaphragm and a wide selection of diaphragm and lower-housing materials to match the process media. The model 101 adds a flushing port for easy in-place cleaning when the media is prone to clogging or solids buildup.
