Elongated cones are tapered to fit
snugly around glass [ST] joints to keep them from
seizing, leaking, or galling. Constructed of virgin PTFE
film with an approximate thickness of 0.05mm. Sleeves
eliminate need for lubricants or adhesives, are
chemically inert, and preclude contamination. Made to
withstand temperatures from –100 to 250°C.
