What it is
The Fischer Pup M3 gun is an applicator for foams and sealants supplied as a complete set comprising 1 PUP M 3 gun and 2 extensions, useful for reaching difficult spots and for dispensing the product even in hard-to-access areas. Designed for an M3 thread, it is supplied in a box in a pack of 1 piece.
These are guns, nozzles, static mixers, extensions and hole-cleaning brushes for correctly dispensing adhesives, sealants, foams and chemical anchors.
What it is for
Used for structural and assembly bonding, for thermal insulation of walls, roofs and pipework and for sealing joints, gaps and service penetrations.
How to use it
Choose the gun suited to the format (cartridge, foil pack, foam can or dual cartridge for chemical anchors) and fit the nozzle or mixer, cutting it to the bead size. Dispense with steady pressure; with chemical anchors, discard the first extrusions until the colour is uniform, and clean the hole first with a brush and blow-out pump. After use, release the pressure and clean the gun.
