Our O-rings are available in different materials and designs to meet specific performance needs, from high-pressure environments to low-temperature sealing. Whether you need standard O-rings, metric O-rings, or specialized quad rings (X-rings), our sealing solutions ensure optimal performance and longevity in any application.
Our standard O-rings feature a simple donut-shaped design, perfect for basic sealing applications.
Known for their high oxygen permeability, silicone O-rings are widely used in wastewater aeration systems and applications that demand high-temperature stability.
Quad rings design that enhances their sealing ability, providing greater stability and reduced friction in dynamic applications.
HNBR O-rings offer enhanced resistance to extreme temperatures and ozone exposure, making them suitable for the automotive, oil & gas, and aerospace industries.
For applications that require higher pressure resistance, square O-rings offer enhanced dimensional stability and durability.
FKM O-rings are engineered to resist extreme temperatures, chemicals, and fuels, providing superior sealing performance in high-pressure and high-temperature applications.
