1 Internal diameter unless specified OD (outside diameter).
² These elements are bagged dried, unless specified WET, before shipping.
3 The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Others pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
