Zoro Select Buna-N O-Ring Dash 011
This pack contains 100 Buna-N O-rings sized to Dash 011 for sealing applications. They suit maintenance technicians and engineers who need a reliable supply of standard inch-dimension seals. The rectangular cross-section profile fits corresponding grooves in hydraulic and pneumatic assemblies. Each ring is black and made from nitrile rubber.
FDA approved material with 70A durometer
The Buna-N compound carries FDA approval for incidental food contact and has a 70A durometer hardness rating. This medium-hard specification determines whether the seal meets the required extrusion resistance and chemical compatibility for a given fluid system. The material is metal detectable but not X-ray detectable.
Temperature range from -40 to 250 degrees F
The seals operate continuously across a range of -40 to 250 degrees F, covering most general-purpose industrial environments. They handle common hydraulic oils, water and air lines within this window. The compound reaches its limit with aggressive solvents, high-temperature steam or prolonged exposure above the rated maximum.

Questions about this item
What does the 0.3 in inside diameter mean for the groove I machine?
The actual inside diameter is 0.3 in and the actual cross-section width is 0.07 in, so the groove should be sized to those dimensions for a proper seal.
How does the rectangular cross-section affect the seal compared to a round one?
The rectangular profile provides a larger sealing contact area and resists rolling in the groove, which helps maintain a consistent seal under pressure.
What groove width and depth do I need for this dash 011 ring?
Design the groove for an actual width of 0.07 in and an actual outside diameter of 0.441 in to match the ring's rectangular cross-section.
