continuous-duty design
The Ashcroft Type 311/312 midi-seal features all-welded construction to eliminate possible leakage of the process media; many process connections including 1 inches male NPT; and a flushing connection for easy cleaning in applications where clogging could occur. Seal can be used with switches, transducers, and digital gauges. It can also be used with two sizes of Bourdon tube gauges – 3 1/2 inches and 4 1/2 inches.
