SANITRX HPX® II Rupture Disc

The pharmaceutical, biotech, food and beverage industries rely on the high-precision SANITRX rupture disc family – the perfect combination of industry-leading performance with ASME BPE and USP Class VI compliance.

The SANITRX HPX II Rupture Disc is a semicircular scored, reverse-acting rupture disc designed specifically for applications that require pressures above SANITRX HPX’s specifications.


The versatility of the SANITRX HPX II

SANITRX HPX II rupture discs can be used in a wide range of sanitary and hygienic applications throughout pharmaceutical, biotech, food and beverage facilities. They fit between industry-standard sanitary ferrules, NovAseptic flanges or SANITRX fittings.

To optimize service life and rupture disc performance, we manufacture and test each order of SANITRX HPX II rupture discs at your specified compressible or incompressible relief conditions.

Fluoropolymer coating is available for corrosion protection on process or vent sides. Electropolished surface finishes are also available. ASME Code Section VIII, Division 1 compliance available when requested.

ASME BPE Standard

The SANITRX HPX rupture disc family is in compliance with the essential criteria of the ASME BPE standard as follows:

  • Clean-in-place and steam-in-place cleanable
  • Withstands temperatures of 130°C where steam sterilization is required
  • Internal surfaces and sanitary fittings meet SF1 (20 Ra microinch) standard surface-finish requirements
  • USP Class VI-certified gaskets are fully traceable, include no animal derivatives and meet other ASME BPE standards
  • 316L SS fittings are standard; alternate materials are available
  • Fully traceable materials
  • Fittings are marked and packaged in accordance

This standard provides requirements applicable to the design of equipment used in the biotech, pharmaceutical and personal care industries, including aspects related to sterility and cleanability, materials of construction, dimensions and tolerances, surface finish, material joining and seals.

The standard applies to components in contact with the product, raw materials or intermediates. Systems that are a critical part of the manufacturing process, such as water for injection (WFI), clean steam, filtration and intermediate storage may also abide by this standard.

Sanitary packaging

The SANITRX HPX rupture disc family is shipped in sanitary, nontoxic, environmentally friendly packaging.

Benefits include:

  • Plastic packaging eliminates direct contact of the rupture disc with open cell material, such as cardboard or foam, which can carry contaminants or leave particles on the rupture disc
  • Clear packaging provides visibility of the rupture disc tag, allowing verification of the rupture disc specification without removal from the package
  • Recyclable plastic package and cardboard carton
  • Combined with the vertical tag, the new plastic packaging provides a compact, space-saving container for the rupture disc

Nominal Size Range: 1 1/2″ – 4″ (40 mm – 100 mm)

Burst Pressure Range: 10 psig – 500 psig (0,689 barg – 34,5 barg)
