Silicone Stoppers from Sinclair & Rush.
Our Silicone Stoppers, also known as Silicone Tapered Stoppers or Silicone Plugs, are the industry standard for high temperature masking applications. Made from High Temperature Silicone Rubber, this reliant material is suitable for use during Powder Coating, E-Coating, Plating and Anodising. With a rating of up to 315°c, our range of High Temperature Masking Bungs can be used for all general plugging applications. Recommended operating temperature range is -65°c to 230°c.
The tapered design of our Silicone Stoppers means that a tight seal is easily achieved simply by pushing the Plug into the hole that needs to be masked or closed off for your process. These Tapered Silicone Plugs are suitable for threaded or non-threaded holes.
We offer a standard stock range of Silicone Stoppers 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.
Silicone Tapered Stoppers are commonly used during Powder Coating, E-Coating, Plating and Anodising. Not recommended for use with aggressive chemicals or hydrocarbons. (See our EPDM Stoppers for this).
*Tip - ensure the Major Diameter is at least 15% larger than the hole diameter and the Minor Diameter is at least 15% smaller.

I would strongly recommend S&R to anyone looking for someone to manufacture plastic parts, from both a development and service prospective.
We have had the absolute pleasure of working with Sinclair & Rush since 2009. Over the course of our relationship, they have supplied a high level of customer service and quality which we are extremely grateful for. And we look forward to working with them further in the years to come.

S&R are very service-minded, and always ready to help. You can always call them, and get info on stock, leadtime and prices on all their items. If you have any request on other parts, they are more than happy to help you with that too.
