Ultra-Chemical-Resistant Kalrez 4079 O-Rings
Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance. Use them with acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids. They have a round profile and are suitable for a wide range of static and dynamic sealing applications.
Inch O-rings have a dash number and are sized to the SAE standard AS568.
Metric O-rings are sized to the actual measured inside diameter.

Ultra-Chemical-Resistant Kalrez 4079 O-Rings for
Tube Fittings with Straight-Thread Connection
Also known as Boss O-rings, these Kalrez 4079 O-rings are for use in tube fittings with a straight-thread connection. They’re inherently softer and more compressible than PTFE O-rings with comparable chemical resistance. Use them with acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids. All have a round profile and are suitable for a wide range of static and dynamic sealing applications. These O-rings are sized to the SAE standard AS568.
