Screw-Type and Tite-Seal Rupture Disc Holder Assemblies

Give your miniature pressurized systems dependable, instantaneous overpressure relief with the Screw-Type rupture disc holder and the Tite-Seal assembly – customized for small systems, such as air conditioning systems, refrigeration units, hydraulic accumulators, gas cylinders, portable compressed-air systems and laboratory equipment.

Screw-Type and Tite-Seal assemblies are available with a variety of inlet and outlet connections to accommodate various applications.

The Screw-Type rupture disc holder

The Screw-Type assembly is a reusable unit for use in systems with pressures up to 15,000 psig (1034 barg).

A Standard, Composite, or SRA rupture disc is supplied separately from the Screw-Type holder. After an overpressure condition occurs, changeout is accomplished by disassembling the Screw-Type holder and replacing only the burst rupture disc.

Various pressure ratings, materials and holder configurations are available to customize the Screw-Type assembly to your specific application.

The Tite-Seal assembly

The Tite-Seal assembly is a sealed, disposable unit for use in systems where pressures do not exceed 3,000 psig (207 barg).

The Tite-Seal assembly features a rupture disc sealed between brass fittings. After relieving an overpressure condition, changeout is easily performed by replacing the entire assembly.

The Tite-Seal assembly can be supplied with a Standard, Composite or SRA rupture disc to accommodate various applications.
