PTFE AS568 O-Rings (AKA Teflon® O-Rings)
PTFE O-Rings, also known as Teflon® O-Rings, are built for customers who need extreme chemical resistance and high temperature performance where standard elastomers fail. These O-Rings are made from polytetrafluoroethylene, one of the most chemically inert sealing materials available, making them highly resistant to acids, bases, oils, solvents, and steam. With an operating range from -100°F to +500°F, PTFE O-Rings perform reliably in aggressive environments like chemical processing, valves, and analytical equipment. Because PTFE is a rigid, non-compressible material, proper groove design is critical to achieve an effective seal. The benefit to you is longer service life, reduced chemical attack, and fewer failures in demanding applications where downtime is not an option.
