Rupture discs for protecting equipment against overpressure
Founded in 1945 · Headquarters: Blue Springs, Missouri, USA
Who is Fike and what does it make?
Fike is an American manufacturer of rupture discs for protecting equipment against overpressure, active since 1945 and based in Blue Springs, in the state of Missouri. From the Fike range we can quote reverse-acting rupture discs from the G2 family (the RD500 Atlas and RD520 Axius series), forward-acting discs from the standard range (Poly-SD, SCRD, HOV, AD, P series) and hygienic discs for sterile applications (Axius SC, RD540 SC). The company also produces custom discs, designed for specific process requirements.
A rupture disc complements or replaces a safety valve where the process requires instantaneous opening, with no leakage until the moment of rupture, or where the conveyed fluid would clog a conventional valve. Fike mentions its own ASME-certified flow characteristics test laboratory, and offers technical guidance through Technical Bulletin 8100 (document 8100) on the requirements for rupture disc devices.
For installations in Romania, Fike discs make sense on chemical reactors, sterile pharmaceutical lines and pressure equipment in the food industry, where overpressure protection must react instantly, with no moving parts that can jam.
What do we supply from the Fike range?
| Product | Description |
|---|---|
| G2 Rupture Discs (RD500 Atlas, RD520 Axius) | Reverse-acting rupture discs from the G2 range, designed for high accuracy of the stated burst pressure and repeatability between batches. Used on reactors and pressure vessels where the tolerance on the opening pressure must be tight. |
| Standard Forward-Acting Discs (Poly-SD, SCRD, HOV, AD, P Series) | A family of forward-acting rupture discs, for general overpressure protection applications, where accuracy requirements are less strict than for the G2 range. The choice of model depends on the burst pressure required and on the compatibility of the material with the process fluid. |
| Hygienic Discs (Axius SC, RD540 SC) | Rupture discs for sterile applications, with a design that avoids areas that are hard to clean, intended for pharmaceutical and food lines where cross-contamination must be ruled out. |
| Custom Discs (Specialty) | Rupture discs designed to specific process requirements — pressures, temperatures or materials outside the standard range — for unusual applications. |
Why Fike?
- G2 reverse-acting range (RD500 Atlas, RD520 Axius) for precise and repeatable burst pressures
- Hygienic variants (Axius SC, RD540 SC) for sterile applications in pharmaceutical and food
- Custom discs, designed for specific process requirements not found in the standard range

How do we supply Fike in Romania?
The information about Fike comes from the manufacturer's technical documentation on rupture discs, and the exact pressure parameters for each model remain in the manufacturer's data sheets, not in the general overview that we consulted. We bring in Fike discs to order through EU supply channels, usually within 1–4 weeks of confirmation. For a correct quotation we need the burst pressure wanted, the disc diameter, the working temperature and the material compatible with the process fluid. We cannot provide permanent availability for every model — each order is checked separately before the quotation.
The burst pressures for each series are those in the individual data sheets of each disc model.
Frequently asked questions about Fike
How do I choose the right Fike rupture disc for my installation?
The choice starts from the burst pressure required, the working temperature and the type of fluid in the line. Reverse-acting discs, such as the RD500 Atlas or RD520 Axius, offer tight tolerances and withstand back pressure, making them suitable for critical applications. Forward-acting families, such as Poly-SD or the SCRD series, cover simple applications, from low to high pressures. Final confirmation depends on the nominal diameter and on the compatibility of the material with the conveyed medium.
What is the difference between Fike reverse-acting and forward-acting discs?
Reverse-acting discs, such as Axius or Atlas, have tight operating ratios and burst tolerances and resistance to back pressure. Forward-acting ones, such as Poly-SD or HOV, are intended for pressures from ambient up to high. The right selection takes into account the operating ratio required by the installation and the risk of pressure fluctuations in the system.
Do you supply Fike rupture discs in Romania?
We bring in the Fike rupture discs requested to order, based on the code confirmed by the customer, with no stock of our own on this range; the lead time is usually 1–4 weeks. We rely on the manufacturer's data sheets and technical documentation to identify the correct variant. It helps to send the nominal diameter, the burst pressure wanted and the working temperature for a quick match to the right family.
What are the Fike Axius SC hygienic discs?
The Axius SC is a hygienic reverse-acting variant, with no indentations or cracks on the surface in contact with the product, designed for the pharmaceutical and food industries. The surface without indentations or crevices avoids retaining contaminants from the process. It is chosen when the application demands a high level of sanitation and traceability of the equipment installed on the process line.
How do I request a Fike quotation?
Send the Fike code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
