Why Choose Viton Packing?
Viton (FKM) elastomer packing provides significantly greater resistance to petroleum-based fluids, hydraulic oils, acids, and high-temperature media compared to standard EPDM or neoprene seals. This makes the 9038CG33Z20 the preferred choice when system media or environmental conditions could degrade conventional packing materials, ensuring leak-free, long-term performance.
