1131 Differential Pressure Gauge

Brand: Ashcroft Inc
Does not ship to Virginia, United States

The Type 1131 is utilized for applications where migration of the process media is not permissible.

The Type 1131 uses a rolling diaphragm design to separate the high and low-pressure ports to isolate the media and can see up to 3000 psi static pressures.

Body materials are available in Aluminum, Brass and Stainless Steel, with Buna, Viton or EPDM seals.
