Strong Thrust for Smooth Sealing
The HARDEN 15-inch Aluminium Mastic Gun is designed to apply sealants for construction, installation, and repair work. Its sturdy aluminium-alloy body, steel push rod, and high-thrust mechanism support controlled dispensing, while the ergonomic handle and spring-assisted trigger help reduce effort during repeated applications.
Rotating Design and Replaceable Cartridges
The 360° rotating gun body lets you position it at different working angles. Press the release tab and pull back the push rod to replace the cartridge. The gun supports soft-rubber cartridges with a plastic top sheet and hard-rubber cartridges with a metal top sheet, as specified for compatible materials.
Multiple Sealing Applications
Suitable for applying compatible sealants around glass, ceramic surfaces, bathroom fixtures, kitchen equipment, windows, wall joints, and sinks. It is also useful for toilet sealing, aquarium DIY projects, and general household or construction repairs.
