The M4 Silicone Cap x 19mm long
The M4 Silicone Cap is one of the most popular products chosen for covering pins, studs, rods and wires during finishing operations and assembly.
Silicone Rubber caps are suitable for many applications, from general protection to high temperature masking.
Manufactured from silicone rubber, Silicone Rubber caps or BAKEWELL CAPLUGS are ideal for masking during electro-static powder coating, stove enamelling, E-Coat, plating and anodising. The high temperature resistance means they can be re-used over and over. When used as rubber caps, the CAPLUG is simply pushed over the stud or pin requiring masking. As a plug, it is often best to push the Silicone Rubber caps into the hole to be masked, using a radiused end insertion tool, or on larger sizes, the end of a pencil or pen. After processing, the Silicone Rubber cap is simply removed, while the component is still hot. Any coating build up can be removed manually, or in a rumbler. Popular sizes are colour coded to assist in selection and identification. The table shows the range available and what parts best suit the threads to be masked.
