Super-Resilient Ultra-Chemical-Resistant DuPont Kalrez 7075 O-Rings
Made for demanding applications, these Kalrez 7075 O-rings hold their shape even after repeated rubbing or compression. More durable than Kalrez 4079 O-rings, they also have higher tensile strength and heat resistance. They can withstand a wide range of chemicals, including acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids.
