Two items to follow up here:

1. I found out that Keck (Germnay) makes an adapter to convert barbed host fittings to GL-14 fittings.  My company doesn't sell these, butt Cole Parmer and others do.  See, for example,  http://www.coleparmer.com/catalog/product_view.asp?sku=0684151

2. I should have mentioned that a competent glassblower can easily convert existing barb connections to GL-14 connections like those I referenced below.  As always, be sure the glassware is scrupulously clean before giving it to your glassblower!

The better solution is condensers that have removable hose connectors.   See, for example, http://www.safetye mporium.com/?CG-1213-A-HC-01 or look on http://www.safetyemporium.com/ILPI_Site/WebPagesUS/lab/condenser.htm for additional styles.
