Weather Sealed Dial Cases
All Orange Research differential pressure gauges and flow meters are weather sealed to keep out water or dust.
We incorporate a gasket behind each lens which protects the front of the dial case. There is also a gasket between the back of the dial case and the pressure body. The materials we use in the components are designed to withstand all weather environments.
The design itself also keeps out water or dust. We have kept the number of ingress points to a minimum and have strong, binding screw-on bezels that cannot be removed or installed without a tool. The gasket seals are designed and tested for the proper compression and weather resistance. So, there is simply no access for weather to invade the dial space of Orange Research gauges.
