PEECO Weather-Proof
Flow Switches
For Non-Hazardous Locations with Maximum Allowable Pressure to 600 PSI
Encompassing all the
features and reliability of our more popular Explosion Proof
models, these units are furnished with a slip-on steel cover. This .062 thick
housing is NEMA 4X weather proof, by utilizing
a special "O" ring seal fitted into a mechanical groove
in the body; a standard on all of the non-explosion proof models.
The housing & cover are both made of heat treated aluminum
T-356 and are epoxy coated (for extra protection). Each of the
four basic styles shown are adaptable to many other fittings
and configurations.
