Semco Fillet Nozzles are used to apply covering lap joints with sealant fillets. These nozzles boost productivity by removing the need to tool the sealant with spatulas.
The built-in step on the fillet nozzles directs the nozzle along the lap joint to create a uniform, smooth fillet. The type 429 nozzle has no steps, making it versatile for usage in tight places and at strange angles.
Each time a fillet is sprayed with these nozzles and a Semco® model 250 sealant gun, it will be smooth and uniform.
The models 425, 426, 427, and 428 nozzles have a built-in step to guide the nozzle along the lap joint. It produces a smooth, uniform fillet. The model 429 nozzle has no step, offering versatility when used at odd angles and confined spaces.
These disposable nozzles are precision molded and have a 1/4″ NPT male thread to fit Semco® 1, 2-1/2, 6, 8, 12, 20, 32 oz. and 1/10 gallon disposable cartridges. When these nozzles are used with a Semco® 250-A sealant gun, a smooth, uniform fillet can be applied each time.
