The compact size of the Ashcroft 310 and 315 mini-seal allows it to fit into space-restricted areas and is designed to protect transducers, mini-switches, and 3-1/2" or smaller dial size pressure gauges from corrosion, plugging or freeze- up.
All-welded metal construction prevents leakage of process media. It is rated for 2500 psi at 100°F and has a 316L stainless steel top housing standard. Lower housing materials include 316L stainless steel or Hastelloy® C.
Diaphragm materials include 316L stainless, Hastelloy® C or Tantalum. 1/4" NPT or 1/2" NPT process connection sizes are available.
