Buna-N Nitrile (NBR) 90 Duro Round O-Ring Cord

Round O-Ring cords are the most common type of O-Ring. They are used for both static (non-moving) and dynamic (moving) applications. The round profile is very versatile and can provide an effective seal for a wide range of pressures, temperatures, and fluid types. In a properly designed sealing groove, a round O-Ring can deform under pressure to fill the gap and prevent the passage of fluid.

One of the key advantages of O-Ring cord is that it can be cut to the exact length required and joined to form an O-Ring of a specific size. This is particularly useful for large or non-standard sizes, where a pre-made O-Ring may not be readily available. However, a joint in an O-Ring can be a potential weak point, so this approach is typically used for less critical applications or when the operating conditions are not overly demanding.

As with any type of seal, the effectiveness of an O-Ring is highly dependent on the specific application conditions, including pressure, temperature, the type of fluid being sealed, and the mechanical design of the sealing groove. The decision to use a round Buna O-Ring cord or any other type of O-Ring should be based on a thorough consideration of these factors.
