Bell & Gossett 108122 Monoflo fitting with 1-1/4" x 1/2" connections for hydronic heating systems. This fitting is designed for use in hot water heating loops to balance flow and ensure proper circulation. Constructed from durable materials for long-lasting performance in residential and commercial HVAC applications.

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.
