3-A Standard Certified Compound Engineering

Parker currently offers gaskets with both the plastic and rubber portions certified to 3-A standards. Based on the environment, different elastomers can be recommended.

The 3-A certified elastomers (3-A Certificate Authorization Numbers 1609 and 1610) are:

• Silicone (S0317-60) – A red colored material that offers the widest temperature range of all the material choices - going from -65°F to 400°F. This material is good in dry heat and has good ozone resistance. This material is acceptable for use with milk or edible oils. This material does not contain any animal-derived ingredients.
• Fluorocarbon (V1274-80) – A black colored material that offers good high temperature resistance capabilities – having a temperature range of -15°F to 400°F. This material has excellent resistance to ozone, oxygen, aromatics, and many organic solvents and chemicals. This material is acceptable for use with milk or edible oils. This material does not contain any animal-derived ingredients.
• EPDM (EJ590-70) – A white material that offers good temperature resistance – having a range of -65°F to 300°F. This material is the recommended material for optimal steam and water resistance and also has excellent ozone resistance. This material is acceptable for use with milk or edible oils.
• Nitrile (N1069-70) – A black colored material that offers a temperature range of -30°F to 200°F. This material has excellent wear resistance – but is not as resistant to ozone as the other materials offered. This material is acceptable for use with milk or edible oils.

Gasket Engineering
Parker's (compression limited) sanitary gasket increases long-term sealability, offers excellent wear performance and complete material traceability – while greatly facilitating installation and removal.
Compatible with all ASME-BPE hygienic clamp unions, Parker's design offers minimal intrusion (± .003" compared to industry average of 0.050”) mitigating the entrapment of any media, the reduction of fluid flow or creation of turbulent flow (that may disrupt cell cultures) - all of which can lead to microbial growth and contamination.
In addition, there are alignment tabs to correctly and quickly ensure correct alignment. The controlled compression limiter minimizes the need to re-torque, promotes the integral long-term condition of the gasket and prevents erosion of the elastomer. Of equal value, these features have the added benefit of exponentially reducing general maintenance and servicing labor costs.
All Parker compounds are certified FDA, 3A and USP Class VI, unlike many of our competitors who are only compliant. Where applicable, Parker compounds are also ADI Free.
