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.

If you have a Jandy backwash valve and the purple (lower) o-ring breaks often like mine did this is the exact size needed and is cheaper than buying the backwash repair kits that have the o-rings and other parts included. I hope it last longer than the o-rings that came with the repair kits.

Fits perfectly inside a 2"pvc tube. Seals well and rolls, so filling and squirting are a breeze.

I bought these to make PVC water cannons. They fit perfectly around 1-1/4" sched. 40 and inside 2" sched. 40 to create a seal. Unfortunately, the water cannons are too big, heavy and difficult for my four-year-old son to operate, so now I need to rework my design using smaller diameter PVC and find the right o-ring for the job. I only needed two o-rings, but it was only a couple bucks more to buy 50.
