Forming a seal at a filter, an upper mold section is placed over a molding groove at the filter, giving a hollow zone to be filled with an injected sealant To fit a seal (16) in a seal holder (4), e.g. as a groove (6) at a filter (2), an upper mold section (8) is placed over the holder with the shape of the seal to be formed. A fluid sealant is injected into the hollow zone (10) formed between the upper mold and the holder, and is allowed to set. When the seal is hard, the upper mold section is removed. The sealant is fed by a dosing unit (12) with an injection channel (14).
