Seal a variety of faucet components so they don't leak.

With a range of sizes on hand, you’ll always have the right O-ring for the job. Made of Buna-N, the O-rings in these assortments resist grease, hydraulic oil, and motor oil. They also withstand mild chemicals and water, although they’ll break down from exposure to brake fluid. Their resistance to compression and tearing helps them keep their shape over time, so they’re often used to seal power transmission assemblies and pneumatic cylinders.

Insert these washers in the threaded female end of a garden hose fitting to prevent leaks.

Safe to use in drinking water, these washers meet strict NSF/ANSI 61 standards. All are made of EPDM rubber, so they won’t break down from exposure to water.

Keep a variety of sizes handy so that you always have the O-ring you need. The HNBR O-rings in these assortments are a step up from Buna-N O-rings—they contain extra hydrogen to better resist chemicals, weather, and abrasion. They won’t swell from contact with grease and acid, making them a good choice in engine, hydraulic, and HVAC systems. Because they won’t deteriorate from ozone, UV, or oxidation, these O-rings are also good for outdoor use. However, they won’t withstand solvents or strong acids like Viton® fluoroelastomer O-rings do. They’re also known as hydrogenated nitrile and highly saturated nitrile O-rings.

Made of SBR rubber, these washers won’t break down from exposure to water. Place one washer inside a nozzle or spigot to prevent leaks at the connection point. The _5/8" ID washer is commonly used in garden hoses.
