Terwin “TEBP” Series
Extrusion Burst Plugs

The Terwin TEBP‐Series burst plugs are specifically designed for use in extruders where the maximum
process temperature does not exceed 410°C (750°F).

The TEBP Series is designed to provide a reliable last line of defence against the build up of excessive
pressure.  The instantaneously rupture at a predetermined pressure.
