Therefore, it quickly indicates low air or non-corrosive gas pressures–either positive, negative (vacuum) or differential.
The design resists shock, vibration, and over-pressures.
Service: Air and non-combustible, compatible gases.
(Natural Gas option also available upon request.)
Pressures must be less than 35 psi for use with hydrogen, while with Buna-N diaphragm too.
