Mushroom Jar Lid for Grain Spawn Stainless Steel Metal Wide Mouth (6 Pack)

ProLid professional series wide mouth stainless steel mason jar lids are engineered for reliable repeated use and lasting durability. Designed to make hundreds of runs through the autoclave or pressure cooker. ProLids offer a combination of unique features, not found anywhere else. Made of 304 Stainless Steel metal to prevent the rusting of standard metal lids. A solid one-piece design and construction makes them simpler to make use of and clean. Every lid includes a fitted silicone seal that stays in lid when held upside down. These lids feature an enormous 1/2″ heavy duty self-healing injection port and a top of the range 0.45 PTFE filter sticker. These industrial strength components mean you’ll rebuild them less continuously. Even while you do, replacing an injection port is super easy, because they fit snug and require no sealant or mess. We sell replacement parts for all our lids. PLEASE NOTE: This version is designed specifically for grain spawn cultivation (not liquid culture), because they feature a PTFE filter sticker, which can’t be held upside down with liquid. If you need lids for liquid culture, which can be leak proof upside down, checkout our other listings.
