Custom Pressure Relief Solutions for your Extrusion Equipment
Tempco’s Extruder Rupture Discs are pressure relief devices designed for overpressure protection of plastic extruders. A rupture disc is soldered or welded to the end of a threaded hollow bolt to fit flush in the extruder barrel. This prevents plastic buildup and hardening that might render the rupture disc ineffective. Tempco carries a number of sizes to fit standard thermocouple wells to serve as replacements for expended units.
