M14x1.5 Extruder Rupture Disks

All Pressure Ranges & Lengths Ship from Stock!

Standard Lead Times


Built to the most common specifications used in the plastics industry, MPI’s M18x1.5 thread extruder rupture disks are compatible with Dynisco, Gefran, Oseco and Fike units. M18x1.5 thread rupture disks are often used on larger European-manufactured extruders that require a larger rupture disk size to allow larger plastic discharge during safety relief.

While Inconel is our standard rupture disk material, thanks to its stability over a wide temperature range, other materials are available for special applications. Contact us to discuss your custom requirements.
