The throwaway holder assembly is a disposable unit that features a rupture disc sealed between brass fittings. After an overpressure condition, the entire assembly can be quickly removed and replaced with a new assembly. The Throwaway Holder Assembly is a sealed, disposable unit for use in systems where pressures do not exceed 3,000 psig (207 barg).
Our throwaway units are meticulously manufactured with accuracy and reliability in mind. Before shipping, we inspect every throwaway holder with an ultrasonic thickness gauge.
Throwaway units are often found on gas bottles, air conditioning systems, refrigeration units, hydraulic accumulators, gas cylinders, portable compressed air systems, and laboratory equipment.
Throwaway assemblies are available with standard or composite rupture discs. Contact us if you aren’t sure which best fits your application.
