Gaskets

The Gaskets for Evaporator heads are sold in two parts. The gasket itself is the rim that fits between the head and the Evaporator's tube sheet. 2-pass and 3-pass heads use the gasket plus a U-channel that is glued to the rim and fits over the baffles that separate the passes. 2-Pass heads use the U-Channel only on the connection end. The U-Channel adhesive is part number 735026386.
