Vacuum relief must be supplied by normal venting devices, or use our KSEV emergency pressure and vacuum relief vent covers.

When the overpressure has dissipated the cover reseat onto the base.
The series KSEP is available in several materials that are corrosion resistant to most petroleum product applications.
