About this item

  • Made of Buna-nitrile (also called Buna-N) for use with a variety of fluids and hydrocarbons
  • Can be used across a wide temperature range from-30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C)
  • Round in cross-section to provide a seal between cylindrical overlapping surfaces
  • Durometer (hardness) of 70A for resistance to penetration
  • Meets standards defined by Aerospace Standard AS568A


This O-ring is made of black Buna-nitrile, is round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications.

Buna-nitrile can have high tensile strength, and abrasion, tear, and compression set resistance. It can be used in temperatures between -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C), and is compatible for use with petroleum, HFA, HFB and HFC fluids, vegetable oil, alcohol, acids and aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.

This Buna O-ring has a shore durometer of 70A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation.

O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves, and various cylinders. They are circular in shape, with a round cross section, and a hole in the center, similar to a doughnut. O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.

These Buna-nitrile O-rings meet standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

This o-ring is the correct size and perfect fit to replace the original o-ring in the Rubbermaid Reveal Spray Mop. I purchased a second mop only to find that the issue was that the spray bottle was missing the o-ring. Also, this price beat out my local hardware store which offered 2 for half the price of 100. Great buy!

As a review said, it's the perfect size for the Utillian 5 vape. The o ring pack from the head store is like 15 for 2, so this is a killer deal. Splurge and replace them 50 times! Good quality and fast shipping. As advertised.

I didn't want to spend a fortune on the Utllian 5 o ring replacements so I measured out the ring and these fit perfectly. Saved me a ton on upcharged Utillian kit.

Size, composition as stated. Large volume for excellent price. Got probably a lifetime supply for the price of a half dozen or so of similar item with similar specs.

Works well. Make sure this is the size (I.D., O.D., and thickness) that you need. Measure!

Hard to criticize. They fit perfectly and continue to work as expected.

Used these to replace some O-rings in my paintball marker. They seem like they are good quality and so far they are working.

These are great little o-rings. I actually use them for making jewelry components - specifically beaded eyeglass grips. They are the perfect size and thickiness.
