-400 Series - 0.275 -1/4" CS

50 Durometer, Commercial Grade Soft Buna-N O-Rings

Designed for applications requiring soft O-Ring sealing material. Primarily used as a low pressure static seal or gasket. Buna-N compound materials are "standard” for most O-Ring service. While they are not as strong as other Buna-N O-Rings, Soft Buna-N O-Rings require less force to make an effective seal and conform better to uneven surfaces. They are suitable for a broad range of fluids including oils, water, and mild chemicals.
