Product Description
A good seal between glass and cap keeps vacuum, pressure and vapors where they belong. These PTFE/silicone sealing rings combine a chemically resistant PTFE face with an elastic silicone body, giving a reliable seal in bottle and adapter connections. They are a simple, low-cost maintenance item.
This listing is for Kimble catalog number 410171-4226: PTFE/Silicone Sealing Ring, 42 mm. Rings are available in 29 mm and 42 mm diameters and can be steam autoclaved for repeated use. Seat the PTFE face toward the chemical side of the connection, and replace a ring whenever it becomes compressed, cracked or discolored to keep the joint sealing properly. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
