Learn how to get started with your Porthole

• We highly recommend that users familiarize themselves with the Porthole and its components by testing the Porthole with water before first use.
• The gasket is intended to be removable, and may become dislodged when the Porthole is disassembled. This is ok!
• When reinserting gasket, ensure its protruding leg is seated inside the groove, wider side facing out. First, gently press down a few spots around the perimeter, then push any loose sections down- wards into the groove. Avoid stretching the gasket.
• Tighten first screw with hex key for snug fit.
• Firmly squeeze the glass panes while tightening the second screw for proper seal.
• Squeeze the Porthole around the entire perimeter (like a steering wheel) to ensure that the gasket is properly seated before final tightening.
• Do not overtighten center screw. The screws hold the glass panes in place but gasket compression should come from squeezing the glass panes, not from torquing the screw.
• There are three screens that come with the Porthole. For best flow, always use the coarsest one suitable for your application. For a clean pour, pre-sift small particle ingredients such as tea before arranging in the Porthole.
• Do not insert the stopper when infusing ingredients that expand in liquid, are carbonated, or that may ferment. Increased pressure inside the Porthole may lead to leaks.
• Observe sanitary practices to avoid food borne illness. Many ingredient combinations, espacially oil infusions, can present a breeding ground for bacteria.
