This extension is used to join two extraction tubes from the BHO extractor from this manufacturer. It is made of food grade plastic, since the aluminium in contact with the extraction is capable of extracting harmful chemical elements from the aluminium, such as Cadmium and Magnesium. Therefore, the aluminium has been replaced by plastic.

This food grade plastic can withstand temperatures of -90ºC and pressures of 10 bar/cm².

The extension has an internal thread, to attach an extraction tube to each end.
