nbr o-ring
- June 20, 2019
Nitrile (NBR) is a copolymer of butadiene and acrylonitrile. Due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of -30°F to +250°F, Nitrile /NBR is the most widely used elastomer in the seal industry today. NBR o-rings are very versatile, inexpensive material which contributes to its wide array of applications.
Let's start with the 4200-70 General-Purpose Nitrile Seal. What differentiates this material?
1. Excellent Physical Properties
Parco’s 4200-70 70-durometer nitrile O-rings have excellent physical properties. 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.
2. Excellent Resistance to Compression Set
To perform properly, seals must resist taking a set from compression after being installed. When a seal takes
