Comparison of Oil-Resistant Rubber! Selection Method by Environment for NBR, FKM (Viton), and Silicone
Introducing practical content that includes measures for on-site issues such as "swelling" and "hardening"!
In factories, hydraulic equipment, piping systems, and various industrial machines, "oil leaks (due to oil seal failure)" are a critical issue that can lead to serious equipment troubles, fires, and production line stoppages. To address these leaks, the key to sealing is the use of sealing components such as gaskets and packing made from "oil-resistant rubber." In this article, our company, a specialized trading firm and processing manufacturer of industrial sealing materials, will thoroughly explain the mechanism by which rubber deteriorates in oil, compare the characteristics of representative oil-resistant rubbers (such as NBR, FKM, and silicone), and provide guidance on the correct selection based on different environments. *For detailed content of the column, please refer to the related links.
