SENRISE 5Pcs Black Caulking Gun Caps

The SENRISE **aluminium alloy caulking gun front caps** are a durable and reliable replacement for standard sausage-style rubber gun covers. Made from high-quality aluminium alloy, these caps feature a **hard, wear-resistant design** that resists impact, corrosion, and rust—ideal for frequent use in high-moisture environments like kitchens, bathrooms, or workshops. Unlike flimsy plastic alternatives, the aluminium construction ensures long-lasting performance, even under heavy use, while maintaining a secure seal to prevent adhesive leaks or premature drying inside the glue gun.

Compatibility is a key advantage, as these caps fit most **cylindrical (sausage-type) hot melt glue guns**, making them a straightforward upgrade for tradespeople or DIYers. Installation is effortless: simply twist the cap onto the gun barrel by hand, like screwing on a bottle lid, for a snug, leak-proof fit. The tight seal between the cap, gun body, and rubber cartridge ensures **smooth, even adhesive extrusion**, reducing mess and maintaining the cleanliness of your equipment. With **five caps included**, this pack provides ample replacements for multiple projects or backup for shared tools in professional settings.

Each cap measures **65.5mm in outer diameter** and **23mm in height**, designed to match standard sausage gun dimensions while offering superior durability over disposable rubber covers. The black finish is both functional and professional, resisting stains from adhesives over time. Whether used for tile grouting, waterproofing, or general construction, these caps deliver consistent performance without the hassle of frequent replacements. Note that minor variations in manual measurements or colour may occur due to production tolerances.
