Stockwell Elastomerics is custom gasket manufacturer with a core competence in silicone materials. Typically the gaskets and rubber components made by Stockwell Elastomerics are used to protect electronics from the environment. Conversely, Stockwell Elastomerics’ foam port plugs are used to keep the environment inside the enclosure.
Environmental testing chamber plugs are used for testing high temperature, sub-freezing temperature and humidity. Port plugs from Stockwell Elastomerics can be made to standard sizes for 2”, 3”, 4”, 6” round ports. Also, Stockwell Elastomerics can quickly waterjet cut custom geometries with minimal additional cost.
The pictures illustrate the advantage of a concentric plug, having foam on either side of the cable allows the foam to conform more tightly. Large rectangular blocks and port plugs with custom cutouts are easily produced with minimal additional charge.
Lower cost single layer plugs – in a previous post it was mentioned that the black layered plugs cost less with a shorter lead time; recent events have shifted this. Now the single layer with the grey closed cell silicone foam top layer offers better cost savings.
Stockwell Elastomerics manufactures custom gaskets for a wide variety of industries needing to meet rugged environmental conditions, from high heat, freezing, high humidity. Many OEM customers who buy silicone gaskets also buy custom port plugs for their test chambers.
