Rupture Disc Holders

Use a double-disc assembly to simplify your piping arrangements, eliminate back pressure, detect leaks or create an actuated rapid-opening system. Three holder components (inlet, mid-flange and outlet piece) and two rupture discs make up the double-disc assembly. The first rupture disc fits between the inlet and the mid-flange, and the second goes between the mid-flange and outlet.

When used with our non-fragmenting MICRO X or Composite Flat Seat (FS) rupture discs, the UNISERT Assembly creates an effective seal every time. How? They were made for each other. The UNISERT is a flat seat rupture disc holder designed with superior sealing capabilities and easy installation. For use with any burst or pressure rating of the MICRO X or Composite Flat Seat rupture disc.

Keep your rupture disc clean, accurate and operational with the CLEAN-SWEEP Assembly. Designed for viscous media processes, the CLEAN-SWEEP Assembly significantly reduces dead space in pipe-tee rupture disc assemblies, eliminating product buildup and preventing interference or excessive overpressure. This holder is an ideal replacement for rupture disc assemblies installed off the leg of a pipe tee where product buildup could affect the proper operation of the rupture disc. With the CLEAN-SWEEP Assembly installed, the rupture disc mounts directly adjacent to the process flow.

Where product purity and corrosion resistance are critical, use our Sanitary Rupture Disc Holder Assembly. Quick-release and easy to change, this fitting assembly is trusted in dairy, pharmaceutical, food processing, canning, cosmetic and chemical industries.

Our line of Union holder assemblies provides flexibility in tight piping configurations. These precisely built holders combine remarkable ease of installation with high-pressure ratings in pipe sizes of 2″ (50mm) or less. The Union holder assembly works with standard- or composite-type rupture discs. SRA Union and Union-type holders are available for pressure ranges up to 6,000 psig, depending on disc size and type.

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.
