Standard NBR O-Ring Replacement: Dash Number and Gland Check

Provide the AS568 dash number or measured inner diameter and cross-section with units. Verify dimensions against the drawing or groove because a used ring may be swollen, stretched or compressed. Include dimensional tolerances when ordering a custom size.

Specify the NBR compound and one nominal Shore A hardness with tolerance. Record maximum pressure, temperature, clearance under load and static or moving duty. Confirm whether the gland includes backup rings; ring size alone does not define the complete assembly pressure capability.

Identify exposure to oils, fuels, additives and cleaning chemicals before approving the replacement. For alternative polymers, coated rings or encapsulated rings, review the construction and compatibility separately. Keep part number, size, compound, hardness and batch identification on packaging for maintenance stock.
