Thermic-welded tight bellows<\/span><\/span><\/h4>[vc_column_text animation_delay=”0″ el_class=”testo_template”]They are used when leak-tight protection of the components (i.e. screws, shafts, etc.) is necessary
\nagainst the contamination made by coolants.<\/p>\n

They have good chemical and heat resistance according to the properties of the materials used. Thermic-welded tight bellows are available in various shapes and dimensions.<\/p>\n

Small tooling costs for new moulds should be considered, if not already available in stock.[\/vc_column_text][vc_empty_space height=”50px”][\/vc_column_inner][\/vc_row_inner][vc_separator color=”sky”][\/vc_column][\/vc_row][vc_row element_id=”840365″ css=”.vc_custom_1635159784796{padding-top: 50px !important;}”][vc_column animation_delay=”0″ element_id=”165733″ crp=”480:i:i,480-768:i:i,768-1024:i:i,1024-1280:i:i,1280-1366:i:i,1366-1600:i:i,1600-1920:i:i” el_class=”colonna_tab_template”]
