Frequently Asked Questions
What material is best for my application?
The choice depends on temperature, chemical exposure, and pressure requirements. NBR is ideal for general hydraulic oil applications; FKM/Viton for high-temperature and chemical resistance; Silicone for food-grade and medical; EPDM for water/steam. Please share your working conditions and we will recommend the optimal material.
