Selecting the right material ensures maximum protection against leaks, abrasion, and harsh operating conditions. Let\u2019s explore the differences to help you make a smarter choice.<\/p>\n

What are the key differences between FKM, NBR, and PTFE shaft seals?<\/h2>\n

FKM, NBR, and PTFE differ significantly in chemical compatibility, temperature limits, mechanical properties, and cost, each serving distinct industrial needs.<\/p>\n

FKM shaft seals provide excellent heat and chemical resistance, NBR seals are cost-effective for oil-based environments, while PTFE seals deliver unmatched chemical and thermal durability.<\/strong><\/p>\n
