Parker Hannifin NSF 51 Elastomers
Parker Hannifin NSF 51 elastomer materials are designed for sealing applications involving food equipment, beverage processing systems, sanitary machinery, commercial food handling equipment, and food contact surfaces requiring compliance with NSF/ANSI 51 standards. These compounds are commonly used in O-rings, gaskets, sanitary gaskets, custom molded rubber parts, diaphragms, valve seals, tubing seals, and fluid handling systems where food safety, cleanliness, and material compatibility are essential. NSF 51 approved materials are widely specified in food processing equipment, beverage systems, dairy equipment, packaging machinery, and commercial kitchen systems.
Canyon Components supplies high quality equivalents to many Parker NSF 51 elastomer compounds used throughout food processing and sanitary sealing applications. Our team supports replacement O-rings, gaskets, tri-clamp gaskets, sanitary seals, and custom molded sealing components manufactured from NSF 51 approved EPDM, Silicone, FKM, and specialty elastomer compounds. We also assist with material selection, sanitation compatibility analysis, and compliance support for food grade sealing systems.
Common names include: NSF 51 elastomers, food grade rubber compounds, sanitary sealing materials, food processing elastomers
Trade names include: Parker®, Viton™, EPDM, Silicone, Canrez®
FKM O-rings from Canyon Components providing excellent chemical, heat, and compression resistance in critical sealing applications.

Features of Parker Hannifin NSF 51 Materials
- NSF 51 elastomer compounds are designed for food equipment and food contact applications requiring sanitary material compliance
- Many NSF 51 compounds provide excellent resistance to water, cleaning chemicals, sanitizers, and washdown environments
- NSF 51 approved materials are widely used in dairy systems, beverage equipment, food packaging machinery, and processing systems
- Many compounds also support FDA CFR 21.177.2600, NSF 61, USP Class VI, and EU 1935/2004 requirements depending on material selection
- EPDM and Silicone compounds are commonly selected for sanitary systems due to strong water and steam resistance
- Canyon Components supplies equivalent NSF 51 sealing materials with strong availability, engineering support, and rapid lead times
Limitations of Parker Hannifin NSF 51 Materials
- Repeated exposure to aggressive cleaning chemicals and steam sterilization may reduce service life depending on compound type
- Certain food grade compounds may have reduced abrasion resistance in aggressive dynamic applications
- High temperature food processing systems may require specialty compounds with improved compression set resistance
- Some NSF 51 approved compounds may not provide the chemical resistance needed for harsh industrial processing environments
- Specialized certified materials may involve increased production cost due to regulatory testing and traceability requirements

Food Processing and Sanitary Applications
NSF 51 elastomer materials are widely used in systems where food safety, cleanliness, and regulatory compliance are required. These compounds are commonly installed in food processing equipment, beverage systems, dairy systems, sanitary pumps, valves, mixers, filling systems, and commercial food handling equipment. Material selection depends on operating temperature, cleaning chemicals, steam exposure, product media, and sanitation requirements.
Canyon Components supports food manufacturers, beverage companies, dairy processing facilities, sanitary equipment OEMs, and industrial processors with Parker equivalent NSF 51 O-rings, gaskets, and custom molded sealing components. Parker compound references and sanitary material information can be found in the Parker material offering guide and Parker O-Ring Handbook.
Food Processing Equipment
NSF 51 approved O-rings and gaskets are commonly used in food mixers, fillers, conveyors, slicers, and processing systems requiring sanitary sealing performance.
Beverage Processing Systems
Beverage systems frequently use food grade elastomer seals exposed to water, syrups, cleaning chemicals, carbonation, and sanitization cycles.
Dairy Processing Equipment
Dairy systems commonly require sanitary EPDM, Silicone, and FFKM compounds resistant to steam cleaning, CIP systems, and washdown environments.
Sanitary Pumps and Valves
Food grade pump and valve systems utilize NSF 51 approved O-rings and sanitary gaskets requiring reliable long-term sealing performance.
Packaging Machinery
Food packaging systems frequently use elastomer seals exposed to oils, water, temperature cycling, and repetitive equipment movement.
