TANK FITTINGS DESCRIPTION Airtrol Tank Fittings help establish the proper initial liquid level in the compression tank when filling the hydronic system.

Airtrol Tank Fittings must be used with the appropriately sized In-Line Airtrol or Rolairtrol air separator. Tank Connection is 1/2" Male, Boiler Connection is 3/4" Female.
