Detailed Engineering Specifications

A proven choice for industrial professionals, this Buna-N O-ring features an inside diameter of 2.094 inches, an outside diameter of 0.834 inches, and a cross-section of 0.116 inches. Buna-N (Nitrile Butadiene Rubber) is renowned for its excellent resistance to oils, fuels, and many hydraulic fluids, as well as good abrasion and tear resistance. This makes it a superior material for static and dynamic sealing applications where exposure to hydrocarbons is prevalent. The carbon steel specification, while unusual for a standard O-ring material, suggests a potential custom application or a protective outer component not detailed here; typically, O-rings are elastomer-based without a metal substrate for their primary sealing function. For standard O-ring applications, the Buna-N material itself provides the sealing integrity.

Installation Procedure

1. Ensure the mating groove is clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the component and gently guide it into the groove, avoiding any sharp edges or excessive force. 3. Verify the O-ring is seated evenly and without twists or damage before assembling the mating part.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Installing on a dirty or damaged groove.Thoroughly clean and inspect the groove for any imperfections that could cause premature failure.
Using excessive force or sharp tools during installation.Handle the O-ring with care and use appropriate lubrication to ease installation, preventing nicks or tears.
Over-stretching or twisting the O-ring during placement.Gently stretch only as much as necessary to fit and ensure it sits flat and untwisted in the groove.

Common Applications

  • Hydraulic systems
  • Pneumatic cylinders
  • Fluid power equipment
  • Fuel and oil handling

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding Buna-N's operational limits.
  • Avoid exposure to strong oxidizing acids, ketones, or esters, as these can degrade Buna-N.
