Replacement silicone flat nozzles for sealant application — durable, precise, and easy to fit. Key benefits Broad compatibility: Fits plastic bottles or dispensers with outer teeth sized 5 mm or 19.5 mm. No additional fittings required for 14.5 mm outer teeth — these attach directly. This wide compatibility reduces the need to buy multiple nozzle types. Durable silicone material: Made from silicone gel for repeated use. The material resists tearing and maintains shape, reducing leaks and breakage during application. Precise control for every joint: The set includes a complete range of flat nozzle profiles so you can match nozzle width to the job, from narrow gaps to wider joints. Flat tips deliver an even bead and consistent coverage. Secure fit and easy installation: A 4 mm inner wire diameter ensures a snug, stable seat when mounted on sealant tubes or sealing pipes. Attach the flat nozzle to the tube, and it stays in place during use. How this solves common problems Eliminates messy application by providing controlled, consistent bead shapes suited to the gap size. Reduces downtime and waste caused by damaged or leaking tips. Avoids compatibility guesswork by covering the most common outer-tooth sizes and offering a direct-fit 14.5 mm option. Practical use scenarios Bathroom and kitchen sealing: Apply silicone or acrylic sealant cleanly around showers, bathtubs, sinks, and countertops where uniform, watertight beads are required. Window and door installation: Create neat, controlled sealant lines around frames to prevent drafts and water ingress. General construction and repairs: Use for sealing joints in siding, flashing, gutters, and other building joints where different bead widths are needed.
