Bell & Gossett 112010 1/2" ATF-12 Airtrol Fitting (For 12"-14" Compression Tank Dia)

Airtrol Tank Fittings help establish the proper initial liquid level in the compression tank when filling the hydronic system. They maintain proper system pressurization by directing released air to the compression tank and permit cooler liquid flow to the boiler during the off cycle. These fittings must be used with appropriately sized Airtrol or Rolairtrol air separators.
