Meets Your Needs

Excellent Physical Properties; Parco's 4200-70 70-durometer nitrile O-rings have excellent physical properties (see test report on reverse side). For nearly 40 years, 4200-70 O-rings have been used in a wide variety of applications with great results. So when you specify 4200-70, rest assured that you've made the right choice.; Excellent Resistance to Compression Set; To perform properly, seals must resist taking a set from compression after being installed. When a seal takes a set, it no longer exerts force on the mating surfaces, resulting in leakage. A compound with low compression set, like 4200-70, better maintains its elastomeric properties and original thickness, preserving seal integrity. Seals made from Parco's 4200-70 compound provide excellent resistance to compression set. After testing 4200-70 for 22 hours at 212°F, it had a compression set of only 6 percent.; Very Good Resistance; to a Variety of Fluids Nitrile compounds, like 4200-70, provide very good service in gasoline, crude oil, power steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases such as sodium hydroxide.
