- Air Remover (with or without flanges) for direct connection to circulators
- Swivel Isolation Pump Flange complete with integrated Purge Port.
- Residential Boiler Fill Fitting (RBFF).
Each of these items are designed to make installation and initial system fill easier, faster, and trouble free. The new RBFF is a new twist on an old concept. Each RBFF fitting allows for fast and easy isolation of the system expansion tank, a drain valve for easy purging or filling, and a 30 psig pressure gauge for quick and easy check of the system’s current pressure.
