This Pyrex Plug has a flare on each end so no o-rings are required to hold it in place. One end is a smooth dome while the other end has a dome with a 3D shape of your choice. This plug is hand-made and is completely autoclavable and oven annealed for durability. This awesome plug is available in 2 gauge all the way up to 1" gauge and every gauge has a wearable length of 3/8" between the flares.
