    AI Overview
    NBR (Nitrile/Buna-N) O-rings typically use the AS568 dash number standard (001–910) to define dimensions, featuring a cross-section (thickness) and an internal diameter (ID). Common dash numbers, such as 010 (1/4" ID) or 214 (1" ID), specify sizing, while a material prefix (e.g., N0674-70) denotes NBR compound. 
    AS568 NBR O-Ring Size Chart Key (Common Sizes) 
    • Dash 001–050: Nominal 1/16" Cross Section (CS = 0.070" ±0.003)
      • 010: 1/4" ID (0.239" ID, 0.070" CS)
      • 012: 3/8" ID (0.364" ID, 0.070" CS)
    • Dash 110–170: Nominal 3/32" Cross Section (CS = 0.103" ±0.003)
      • 112: 1/2" ID (0.489" ID, 0.103" CS)
    • Dash 210–281: Nominal 1/8" Cross Section (CS = 0.139" ±0.004)
      • 214: 1" ID (0.984" ID, 0.139" CS)
    • Dash 325–395: Nominal 3/16" Cross Section (CS = 0.210" ±0.005)
      • 329: 1-3/4" ID (1.734" ID, 0.210" CS)
    • Dash 425–475: Nominal 1/4" Cross Section (CS = 0.275" ±0.006)
      • 425: 4-1/2" ID (4.475" ID, 0.275" CS) 
    Key NBR O-Ring Characteristics 
    • Material: NBR (Nitrile/Buna-N) is standard for hydraulic/pneumatic applications, offering excellent oil resistance.
    • Durometer: Common hardness ranges from 40 to 90 Shore A, with 70 and 90 being the most common for high-pressure industrial sealing.
    • Temperature Range: Typically -40°F to +250°F (-40°C to +121°C). 
    To find a specific NBR O-ring, determine your ID and Cross-Section to match it with the standard AS568 dash number.

    What does NBR mean in O-rings?
    An error has occurred. Please try again later.
    Is NBR the same as Viton?
    Nitrile is commonly referred to as NBR, while Viton is referred to as Fluorocarbon rubber. Both Viton and NBR have mostly used in industries because they have great compression resistance and other excellent properties. Nitrile and Viton have different properties, characteristics, and kinds of applications.Jul 7, 2021
