O-rings and sealing rings are among the most widely used sealing components in industrial and commercial systems. Despite their simple geometry, their performance depends heavily on material selection. Choosing the wrong elastomer can lead to leakage, accelerated wear, chemical attack, or premature failure, while the right material can significantly extend service life and system reliability.This guide focuses on three of the most commonly used elastomers—NBR, FKM, and EPDM—while also referencing other available options such as Silicone and FFKM. It explains how these materials behave in real operating conditions and how they are applied in practical sealing solutions.A full range of standard and customized rubber O-rings can be found here:https://www.haosealtech.com/O-Ring/Why Material Se...

Rotary shaft sealing is a critical aspect of many mechanical systems, from electric motors and gearboxes to pumps, conveyors, and heavy industrial equipment. A failure at the shaft seal often leads to lubricant loss, contamination ingress, premature bearing wear, and unplanned downtime. Among the many sealing options available, V-ring seals stand out as a simple yet highly effective solution specifically designed for rotary applications.This article explains how V-ring seals work, why they are widely used for rotary shaft sealing, and how material selection, temperature capability, and customization options make them adaptable to a wide range of industrial environments.What Is a V-Ring Seal?A V-ring seal is an all-rubber, one-piece axial sealing element with a distinctive V-shaped cro...
