Set of brass triangular replacement tips for soldering and plastic welding — 16 mm and 21 mm sizes Key benefits Designed for professionals, DIY enthusiasts, and home users who need reliable, precise tips for repair and maintenance. Triangular profile reaches narrow or awkward spots and helps create smooth, even seams on plastic parts. Two sizes (16 mm and 21 mm) provide flexibility for different joint widths and project types. Solid brass construction offers high-temperature resistance and fast heat transfer for consistent performance. Intended as replacement tips for soldering and welding applications where accuracy and durability matter. How this solves common problems Makes it easier to work in tight or hard-to-reach areas where round or flat tips can’t access cleanly. Speeds up plastic seam repairs and reduces finishing work by delivering even heating and controlled material flow. Two size options let you match the tip to the repair area, avoiding overheating nearby parts or inefficient passes. Typical applications Plastic repairs: smoothing seams, joining plastic panels, and fixing split housings. Outdoor gear and watercraft: repairing kayak bumpers, scuffs, and molded plastic components. General soldering and welding maintenance: precise material joining and surface finishing on small to medium repairs. Product details Tip types: triangular profile Sizes: 16 mm and 21 mm Material: brass (durable, high-temperature resistant, fast heat transfer) Use: replacement tips for soldering and welding tasks, suitable for professionals and hobbyists Practical notes Choose 16 mm for tighter seams and finer control; use 21 mm for broader joints and faster coverage. Brass tips heat quickly and transfer heat efficiently; use proper temperature control and steady motion to avoid overheating surrounding material. Designed as replacement tips — verify mechanical fit and mounting method with your tool before use. What makes it stand out Purpose-built triangular shape for access and seam quality. Two sizes in one set for more versatile use. Durable brass construction balances longevity with reliable thermal performance.
