High-contrast colors make it easy to spot when these O-rings aren't seated properly and identify sizes at a glance. Made of Buna-N, these O-rings stand up to motor oil, hydraulic and transmission fluid, and mild chemicals. They’re a versatile choice for sealing in a wide range of machinery, such as hydraulic systems, fuel lines, and air compressors. Each package includes shelf life, cure date, and a traceable lot number.

Best for filling large gaps, these thick shims are commonly used to align cabinets, doors, and windows. Slip them around existing mounting fasteners without unfastening them. All are made of plastic to resist moisture and prevent rot. To reduce sizing errors, these shims are color coded by thickness to quickly spot and grab the right size every time.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

These assortments include rings in multiple colors so you can identify objects at a glance.
