Bell and Gossett expansion tanks help protect hydronic, plumbing, and well water systems from pressure problems caused by thermal expansion and pump cycling. This guide explains how B&G expansi...
Bell & Gossett Airtrol tank fittings are designed to help establish the correct initial liquid level in a compression tank when filling a hydronic system. They also support proper system pressurization by directing released air to the compression tank during operation.
As the system liquid cools during the boiler off-cycle, Airtrol fittings allow cooler liquid to flow back to the boiler, helping support stable system operation. For proper performance, Airtrol tank fittings should be used with the correct size Airtrol Boiler Fitting, In-Line Airtrol, or Rolairtrol air separator.

Bell & Gossett Copper Red Ring Monoflo fittings are designed for single-pipe hydronic heating systems, allowing one pipe to serve as both the supply and return main. These fittings connect risers to the main and help direct the proper amount of water to each heating unit, regardless of the unit type or its position in the system.
Copper Red Ring Monoflo fittings are recommended for many common heating installations, including cast iron radiation, non-ferrous baseboards, free-standing radiation, and connector applications. In most up-feed radiation systems, one fitting is typically enough to provide proper flow diversion. A second fitting may be used when higher resistance is required.
