Kalrez® Sanitary Gaskets Hard to Find? Canrez® FFKM Sanitary Gaskets Are Available Now
Updated: Aug 21, 2026
For years, Kalrez® FFKM sanitary gaskets have been specified in pharmaceutical, biotechnology, chemical processing, food processing, and other demanding sanitary applications. But if you have tried sourcing Kalrez® sanitary gaskets recently, you may have encountered a frustrating problem: they can be increasingly difficult to find.
We have heard this concern from customers looking for replacement FFKM sanitary gaskets for existing equipment and process lines. Rather than waiting on an increasingly difficult-to-source gasket, there is another option.
Canrez® FFKM sanitary gaskets are available now from Canyon Components, with a variety of sanitary gasket styles, sizes, and FFKM compounds available for demanding hygienic sealing applications.
Why Are Kalrez® Sanitary Gaskets Becoming Difficult to Source?
Availability of specific Kalrez® sanitary gasket configurations appears to have become increasingly limited. Customers who have historically specified Kalrez® are sometimes finding that the sanitary gasket they need is difficult to locate or no longer readily available through their existing supply channels.
You need an FFKM sanitary gasket, and you need to be able to get it.
For applications where FFKM remains the appropriate sealing material, Canrez® provides another path forward.
Canrez® FFKM Sanitary Gaskets
Canrez® is Canyon Components' line of high-performance FFKM sealing materials designed for applications involving aggressive chemicals, elevated temperatures, and demanding operating conditions.
FFKM provides an exceptional combination of elastomeric sealing performance and broad chemical resistance. This makes Canrez® sanitary gaskets particularly well suited for process systems where conventional EPDM, silicone, or FKM materials may not provide adequate chemical or temperature resistance.
Canrez® FFKM sanitary gaskets can be supplied for both replacement applications and new equipment designs.
Replacing a Kalrez® Sanitary Gasket with Canrez®
Switching away from a difficult-to-source Kalrez® sanitary gasket does not necessarily mean changing the entire sanitary connection.
In many applications, the first step is identifying the existing gasket geometry and determining the operating requirements. Canyon Components can then evaluate an appropriate Canrez® FFKM sanitary gasket for the application.
Important considerations include:
- Existing sanitary gasket style and dimensions
- Process chemicals and concentrations
- Operating and cleaning temperatures
- CIP and SIP conditions
- Pressure and vacuum requirements
- Regulatory or material compliance requirements
- Existing Kalrez® compound or material specification
Rather than selecting an alternative based solely on brand or appearance, the goal is to identify a Canrez® compound and gasket configuration appropriate for the actual operating environment.
More Than Standard Tri-Clamp Gaskets
When people think about sanitary gaskets, standard tri-clamp gaskets are usually the first style that comes to mind. However, hygienic processing equipment uses many different gasket configurations.
Canrez® FFKM can be considered for a variety of sanitary gasket geometries, including common clamp-style connections and specialty sanitary sealing designs.
Depending on the application, this may include:
- 40MP sanitary gaskets
- 42MP sanitary gaskets
- ASME BPE sanitary gaskets
- DIN sanitary gaskets
- I-Line sanitary gaskets
- Bevel Seat sanitary gaskets
- Custom sanitary gasket geometries
This is particularly useful for facilities with older equipment or specialized process connections where the original FFKM gasket has become difficult to source.
Why FFKM Is Used for Sanitary Gaskets
FFKM is not necessary for every sanitary process. EPDM, silicone, FKM, and PTFE can all provide excellent performance when properly matched to an application.
FFKM becomes particularly valuable when process conditions push conventional elastomers beyond their practical limits.
Broad Chemical Resistance
Sanitary process equipment can be exposed to much more than the product being manufactured. A gasket may encounter the process media itself, cleaning solutions, sterilization chemicals, solvents, acids, bases, and other aggressive fluids during its service life.
FFKM provides extremely broad chemical resistance across many of these environments.
High-Temperature Performance
Elevated process temperatures and repeated cleaning or sterilization cycles can accelerate elastomer degradation.
FFKM materials are designed for high-temperature sealing environments and can provide significantly greater temperature capability than many conventional sanitary gasket materials.
Low Compression Set
A sanitary gasket must continue exerting sufficient sealing force after repeated exposure to temperature, chemicals, and compression.
Low compression set helps the gasket retain its sealing characteristics over time, reducing the likelihood of leakage caused by permanent deformation.
Elastomeric Sealing
PTFE offers exceptional chemical resistance but does not behave like an elastomer.
FFKM combines extremely broad chemical resistance with the resilience and conformability of a rubber sealing material, making it particularly valuable where both properties are required.
FFKM Sanitary Gaskets for Pharmaceutical & Biotechnology Processing
Pharmaceutical and biotechnology applications can be particularly demanding because gasket selection involves more than simply preventing leakage.
Process purity, extractables, cleaning procedures, sterilization conditions, chemical compatibility, and documentation may all influence material selection.
Canrez® FFKM sanitary gaskets can be evaluated for demanding applications involving:
- Pharmaceutical processing equipment
- Bioreactors
- Process skids
- Chemical transfer systems
- High-purity piping
- CIP systems
- SIP systems
Specific compound and compliance requirements should always be evaluated for the individual application.
FFKM Sanitary Gaskets for Chemical Processing
Sanitary-style connections are also used throughout chemical processing and other high-purity industrial applications.
These systems may expose a single gasket to several aggressive chemicals over its service life. A gasket that performs well with the primary process fluid may still fail when exposed to a cleaning chemical or another fluid introduced during a different processing step.
The broad chemical resistance of FFKM can simplify material selection in these challenging environments.
What If You Don't Know Which Kalrez® Gasket You Have?
That is not necessarily a problem.
If you have an existing gasket but do not know the exact size, style, or compound, Canyon Components can help identify the component and evaluate potential replacement options.
Useful information can include:
- Existing part numbers
- Equipment manufacturer and model
- Gasket dimensions
- Photographs
- Drawings
- Previous purchase documentation
- Known process conditions
For difficult-to-identify components, physical samples can also be evaluated to help determine dimensions and material characteristics.
The objective is not simply to find something that looks similar. The replacement needs to fit the sanitary connection and provide appropriate performance for the process.
Kalrez® Sanitary Gasket Alternatives Without Sacrificing FFKM
Difficulty sourcing an existing sanitary gasket does not necessarily mean you need to move away from FFKM.
Canrez® gives engineers, maintenance teams, and purchasing departments another source for high-performance FFKM sanitary sealing solutions.
If you are currently searching for:
