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.

These fit great on various audio and video mounts. They are just the right stiffness. Put them between the screw and the plate and after tightening you can still twist and reposition the mic, light, camera or whatever without having to loosen the screws.

They are very durable and will stretch without breaker.

To call those cock rings is false advertising. Their selling O rings that have no elasticity. No way these could fit on an adult.Take more pride in your product.

No way to know exactly what the material composition is, but it's in an oily hot engine compartment and appears to be ill-affected by the condition. Working great so far

This is what you need to fix Mercedes top hydraulics.

Delivery was fast, and the quality is good. Neither Hardware nor Automotive stores in my area carry this critical product. Low oil pressure in older Japanese cars often leads to the demise of these durable cars. This simple extra-thick o-ring can help restore that pressure. Located between the main engine bearing bridge and the bearing journal inside the engine. It provides proper oil pressure to the crankshaft.

My bead breaker actuator valve on my Ranger R32AT-1 tire changer was leaking due to old o-rings. These o-rings worked great for the fraction of the cost from Ranger.
