Refer to the following terms when checking Cupla specifications. Body Material Seal Material This indicates the material that is used for the plug body or socket body that forms the flow path of fluid through the Cupla. This shows the material used to seal the Cupla, usually an O-ring. Working Temperature Range Sizes This shows the minimum and maximum temperature, in-between which the Cupla with the seal material can be used. However, it does not mean that they cannot be used continuously at the minimum or maximum working temperatures. Please check with us if you need Cuplas in such extreme applications....
