The “Dyhdrator plugs” that Aircraft spruce sells are poor quality and design (fragile, flimsy metal clip to retain fragile glass tube).
The MS27215-2 Dessicant plugs made by ProtekAir appear to be much more robust. (http://spenceraircraft.com/dessicant...ator-plug.html
). I'm looking for a supplier of these in Canada. Do any of you know of one?
