Our Silicone Washer Caps are used to mask studs and protrusions during high temperature coating applications, where there is a need to create a grounding area at the base.
We offer a standard stock range available for next-day delivery and can also assist with any custom enquiries that you have relating to this product. If you cannot find the part you are looking for, or need any help selecting the correct size, please call our Sales Team now on 01634 686504 and we will be happy to assist..
The high temperature rating of the Silicone material means that this product will survive Powder Coating and other forms of plating and coating without melting or burning in temperatures up to 315°C. The flexibility of our Silicone Washer Caps allows them to fit over extrusions, threaded studs, PEMS and dowels, as well as to be used as plugs for threaded or irregular holes. For other high temperature caps, see our options below.
