Bell & Gossett 108124 MonoFlo fitting with 1-1/2" x 3/4" connections for hydronic heating and cooling systems. This cast iron fitting is designed for use in series loop piping to divert flow through radiators or baseboard units. Genuine Bell & Gossett (Xylem) hydronic component.

Monoflo fittings make it possible to use a single pipe to work as both supply and a return to the main supply line on radiators and baseboard heating units. One fitting installation is adequate for up-feed radiation. Two fitting installation should be used when high resistance units are used or units are through a down-feed and require both supply and return risers.
