EPDM(Ethylene Propylene Diene Monomer)

An excellent general purpose elastomer, resistant to many chemicals, polar solvents, many CIP solutions, and most aqueous-based systems. Used for general processing, acid/alkalis, hot water and occasional steaming.
Low permeability to gases. Useful in higher pressure and vacuum applications.
Temperature Range: -20 F° to 300 F°
Continuous Liquid Media: -20 F° to 200 F°

Genuine VITON® GF (FKM)

Used for general processing, most acids , hot water, and excellent steam resistance.
Low permeability to gases. Useful in higher pressure and vacuum applications where both the sealing properties of rubber and the chemical resistance of Teflon® like materials are required.
Temperature Range: 18 F° to 450 F°
Continuous Liquid Media:0 F° to 300 F°

Genuine Dyneon™ TFM™ (Modified PTFE)

Genuine Dyneon™ TFM™ from 3M®.
Resistant to almost all chemicals, solvents, and CIP solutions, It is ideal for continuous steam, hot WFI and processing areas.
Temperature Range (with EPDM backing) : -20 F° to 300º F°
Temperature Range (with Viton® backing):-0 F° to 450º F°

Product Differentiators-Performance

Quality: All materials and parts, are the best grades from the best manufacturers and its own proprietary elastomer formulations.
Reliability: Rigorous testing by third-party industry experts demonstrates long-term durability through 500 steam cycles and more than 100,000 valve cycles.
Maintenance: Less retorquing, plus increased diaphragm longevity equals less maintenance and less plant down-time.
Traceability:Diaphragms are fully batch traceable at the part level an exclusive in the industry (patent pending).
Cleanability: Smoother surface finishes provide better cleanability and sanitization.
