Flare cap, N20, aluminum, bursting cap, hole, butyl light grey/PTFE dark grey, 3.0 mm

Description

Butyl/PTFE closure with good analytical purity. Equivalent closure to 70234.8, only with a punched disk instead of a shaped disk. Very good price-performance ratio. The retaining webs of the predetermined breaking lines of the cap open at an internal cylinder pressure of more than 3 bar (± 0.5 bar) and thus allow excess pressure to escape in a controlled manner. The functionality of the bursting cap does not depend on the design of the rolled edge (beveled or flat rolled edge).
