These high temp silicone rubber plugs are a great fit for the powder coater, custom painter, scientist, handy man, media blaster or anyone who needs premium quality plugs. While most commonly used for masking purposes during finishing, there are hundreds of other uses around the shop, home, lab, classroom, etc. This superior grade of silicone is capable of withstanding temps up to 600 degrees Fahrenheit (315 Celsius) for 20 minutes and holds up to most chemicals. It is ultra tough yet flexible, reusable and will not crack, harden, shrink or break over time. All of our premium silicone goods are color coded for ease of use and the color will never bleed or fade. This size plug is commonly used to mask most 30 ounce stainless tumbler cups to keep custom coatings from getting inside the cup itself - please measure your cup first to ensure the proper fit. Plugs can be easily drilled, cut or modified to fit finishing racks and stands.

I needed to replace a dried out rubber plug on my now vintage Delta woodworking dust collector and I struggled to find something the right size. Lo and behold, this high temperature capable plug is just the thing I needed. I'm hopping that the silicone material will last even longer than the original black rubber one did. So if you are looking for plugs to use with your 4" dust collection system, this is a viable choice.
