Snap-In Pipe and Tubing Grommets
These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. All have a medium-hard rating to withstand high levels of impact. They can be used outdoors.

Electrical-Insulating Rolled-Collar Sleeve Washers
As you tighten your screw, the rolled collar compresses under the head to create an insulating barrier between a screw shank and a mating surface. The sleeve extends into the hole for additional protection. These nylon washers block electrical current and prevent galvanic corrosion from mating different types of metal. Exposure to moisture may cause them to expand.
