NBR O-Ring
- Hardness: 70A
- Temperature: -4℉ (-20°C) to 212℉ (100 °C)
Circular Cross-Section
- They are circular, round in cross-section.
- Designed for use in a wide variety of sealing applications.
- 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.
Nitrile Butadiene Rubber O-rings
- Good mechanical properties and high wear resistance NBR. Good resistance to many petroleum oils, greases, hydraulic fluids, alcohol, mineral oil, and grease.
- 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.

I could not find the right size o-ring to replace the worn piston seal on my harbor freight framing nailer. After taking the old o-ring to my local hardware store and finding they carried every size but the one I needed, I figured out the dimensions and ordered these because they were the right size. They do fit, and my nailer is up and running again.

At 4mm thickness, this O ring will seal for the pressure of pushing down then pickup air for the cylinder in the next cycle.

I needed an oring to seal the plastic plunger on my Chapin sprayer. This is a super quality oring and it was a perfect fit.

Preso in sostituzione di una guarnizione a vista di un rubinetto cucina ikea, calza a pennello.

I couldn’t find a replacement water pipe seal for my import Honda engine (F20B). It fit nice, and no leaks yet (4 months, 10k miles). Seems to stand up to the heat and glycol coolant.
