About O-Rings

Easy-Install Oil-Resistant Buna-N O-Rings
PTFE Coated
A slick surface treatment makes these O-rings easy to seat without tearing or rolling. The lack of friction also helps create a long-lasting seal in dynamic applications, no lubrication required. These O-rings are often used in machine-installed assemblies, such as high-speed packaging equipment. All have shelf life, cure date, and a traceable lot number printed on the bag.
PTFE-coated O-rings have the slickest surface finish of all our O-rings for maximum friction reduction. The coating also acts as a barrier against mild chemicals. It will wear over time in dynamic sealing applications.
