These fittings are made of materials approved for the food industry. They are also suitable in connection with cold or hot drinking water. An O-ring above the cylindrical external thread serves as a pneumatic seal. Special sealants such as Teflon® are therefore unnecessary. These can leave solid residues during screwing anyway, which would contaminate the environment or the medium. Our fittings can be screwed in and out as often as required and always remain pneumatically tight. The selected materials and technologies allow the use of these fittings in the chemical, pharmaceutical, medical and electrical industries. A standard range of these fittings is available. However, other versions can be supplied on request. In this way, Metal Work is able to offer the right solution for every requirement. Translated with DeepL
