Freeze Dryer 3/8" Hose

To help prevent water and particulates from entering your vacuum pump, the new 3/8″ hose can replace your current 3/4″ hose. See additional details below.

 Freeze dryers purchased between January 1, 2015 and November 30, 2019, can replace their current 3/4″ vacuum hose with the new 3/8″ hose. Be sure to check the fittings on your freeze dryer (see image gallery) to make sure this hose is compatible. If you have a different fitting than what is shown, you should purchase the hose insert instead. With this upgrade, you only need to change your oil every 4-5 batches, depending on the quality of your oil. Freeze dryers shipped after December 1, 2019 (and all oil-free pump owners) should already have the new hose or hose insert. Call Tech Support if you have any questions about which one to order, and/or, if this will work with your freeze dryer: 800-865-5584.
